    	The Unity and Authorship of Isaiah:         
    A Needless Battle        
    	Dennis Bratcher           
    The Battle         
    The unity and authorship of the Book of Isaiah has been a touchy subject 
    for many Christians for much of the 20th century. This particular issue has 
    drawn a disproportionate amount of discussion and has usually generated more 
    heat than light. For many, it has become a shibboleth of orthodoxy with the 
    position taken on the issue separating those who believe the Bible from 
    those who don’t.          
    There are various reasons why some have chosen the authorship and unity 
    of the book of Isaiah as a battleground, but a single issue invariably and 
    quickly comes to the forefront: the issue of predictive prophecy. In varying 
    degrees of intensity and from various angles of concern, defenders of the 
    unity and single authorship of Isaiah contend that to concede the book was 
    formed over a period of time would eliminate the amazingly accurate 
    predictive element of prophecy in the book. There is sometimes even the 
    claim made that people who suggest anything differently are really trying to 
    promote an agenda that denies belief in prophecy or the trustworthiness of 
    Scripture.  Or, to argue the other way, they contend that if Isaiah of 
    Jerusalem wrote the entire book, it could only have been God’s direct 
    revelation to him of the things that he predicts, which provides proof of 
    the supernatural origin of Scripture, as well as proof that the future can 
    be absolutely predicted hundreds of years in advance.             
    For example, from this perspective Isaiah names the Persian ruler Cyrus 
    who would overthrow Babylon 100 years before there was even a Babylonian 
    empire and 200 years before Cyrus would be even be born (Isa 44:28, 45:1). 
	This, they believe, is physical proof of the absolutely miraculous nature of 
	Scripture. This is often expanded to include claims of total inerrancy and 
	historical infallibility of the biblical texts. Allowing parts of the book 
	of Isaiah to date after the time of Isaiah of Jerusalem (740-701 BC) would 
	put all of this at risk (see Prophets Date 
	Chart).             
    In other words, the arguments against any suggestion of more than one 
    author or time frame are not usually based on evidence from the book itself. Rather, 
    assumptions about the nature of Scripture and prophecy, certain theories of 
    inspiration, and certain beliefs about how God works in human history 
    provide the conclusion that this must be a single work by Isaiah of 
    Jerusalem. Any evidence is read within that already decided 
    conclusion based on considerations outside the text itself.             
    As a result, many traditional arguments have held for a 
    historical             
    unity for the entire book. That is, all of Isaiah was written by the prophet 
    Isaiah of Jerusalem in the eighth century BC (740-700). As noted, this has 
	usually been promoted as the only way to understand the book, not from 
	analysis of book itself but from certain views of scripture and prophecy. As 
	noted, in modern times, especially since the rise of analytical biblical 
	study in the latter nineteenth century, this has often become a 
    defensive position, an apologetic for predictive prophecy.             
    Such a historical unity for the book fits well with world views 
    constructed from a Platonic/idealistic perspective. This perspective is primarily 
    concerned with ultimate reality and focuses on the total control God exerts 
    on everything that happens in the world, a feature of most theological 
    systems that hold to some form of predeterminism. It also fits well with certain views of 
    prophecy that see its only function as predicting the future, especially as 
    that prediction leads to Christ.  For many this is a primary agenda in 
    arguing for the predictive element as fundamental in prophecy. Actually, 
    however, this is as much a misunderstanding of the New Testament as it is of 
    the Old Testament, but that is another topic.             
    From such a perspective, the "prediction" of the coming of Cyrus in 
    Isaiah 44-45 became the crux of the issue. Either a person believed that this was 
    accurately predicted by Isaiah of Jerusalem 200 years before it happened or 
    one didn't believe any of the Bible. However, this is really arguing an idea 
    of what the Bible ought to be rather than looking at the text on its own 
    terms. Unfortunately, this is still preached from some pulpits, even though 
    it simply is not true. Many people hold the Bible in high regard as the 
    authoritative word of God and cherish it as the basic source for the faith 
    and practice of the church, and yet do not believe that these chapters were 
    written by Isaiah of Jerusalem in 700 BC.             
      It is true that some scholars used the new insights into the origin of 
      the book of Isaiah that emerged in the first part of the 20th century to 
      discount any revelatory actions of God in history. But they had no more 
      basis to take such a position than did those who argued that God himself 
      wrote the book. That was simply an example of the newly developing methods 
      of biblical investigation being used badly. However, some tried to counter 
      such views by rejecting not only the erroneous conclusions, but also the 
      methods of biblical study being used. As a result, often the argument was 
      too strong in the other direction, which resulted for many in a wholesale 
      rejection of the insights into the composition of the biblical books, and 
      Isaiah in particular, that would prove so valuable for others in 
      understanding the dynamic of the biblical message.             
    Assumptions that Support the Battle            
    First, let’s consider some of the assumptions often made in discussing 
    this topic. The problem with many of these assumptions is that they either 
    come from our modern world view and frame of reference without considering 
    how the ancient world might be different, or they work from certain 
    pre-determined beliefs about the nature of Scripture that only allow one way 
    of seeing the text.             
    1) It is often assumed that the title 
    for the book intends to communicate who wrote the entire book. However, the traditional title of a biblical book says nothing about authorship of 
    the book.  Just because the book carries the title "Isaiah" does 
    not imply anything one way or the other about who wrote the entire book. For 
    example, the book of Jonah is not a book written by Jonah, but 
    about             
    him. Similarly, Job, Esther, Ruth, and probably Malachi are likewise not 
    titles of authorship but of content. So, it requires an assumption to 
    conclude that because the 66 chapters of this book fall under the title 
    Isaiah this requires that Isaiah be the author of all of them. And it 
    might be important to recall that biblical book titles are not part of the 
    biblical text itself, but are only traditional titles. Many of the Old 
    Testament books have different titles in Hebrew than they do in English, 
	which are based on titles in Greek and Latin translations.             
    2) Many assume that single books 
    under a single title are the work of a single person. Yet, there are clear examples in Scripture where book titles were applied to 
    collections of material by various authors. For example, the book 
    of Jeremiah contains narrative sections describing from a third person 
	perspective actions that Jeremiah 
    took (ch. 37-44). There are references 
    within the book to Jeremiah’s scribe, Baruch, writing for Jeremiah (36:4-8). 
    So, it seems logical to conclude that these sections were written by Baruch 
    and included with the Jeremiah material without creating a separate book of 
    Baruch (although there is an apocryphal book titled Baruch, which 
    contains edited sections of the book of Daniel, it almost certainly was not 
    written by Baruch). Likewise, the book of Amos contains third person 
    narratives about Amos in addition to the collections of the sermons that 
    Amos himself proclaimed (7:10-17).             
    In a different kind of example, there are several instances where 
    sections of material in one book, Isaiah in particular, are duplicated word 
    for word in another book. For example, Isaiah 36-39 is largely duplicated in 
    2 Kings 18:13-20:19. Also, Isaiah 2:2-4 is repeated in Micah 4:1-3. This 
    suggests that the biblical text is not nearly so concerned with authorship 
    as we are, and that biblical books can be composite from various time 
    periods from various authors without specifically stating that they are so.             
    3) The assumption is often made that 
    the concept of "authorship" is a universal idea that applies to any culture 
    in any time period of human history. But our 
    modern, Western concept of "authorship" is alien to the ancient Eastern 
    world. In our world of copyrights and the legal ownership of 
    ideas, we simply assume that this is also how the ancient world 
    conceptualized intellectual property. In fact, the whole concept of ideas 
    being property that can be owned or sold is a totally foreign concept to the 
    ancient, Eastern mind (as well as some modern cultures; see
	Community and Testimony: Cultural Influence in 
	Biblical Studies). Our assumptions 
    reflect the highly individualized nature of our culture, forgetting that the 
    ancient Near East was far more tribal or communal in its thinking. Ideas 
    were shared within the community and even passed on from one generation to 
    the next as part of the community. This allowed people to teach or write in 
    another’s name, carrying on the tradition of a master through pupils or 
    disciples who would not only preserve the original teachings but add to them 
    as heir of the tradition.             
    There is evidence within the book of Isaiah that Isaiah of Jerusalem had 
    around him a group of disciples, and that he specifically entrusted them 
    with preserving and transmitting his message (8:16,  "Bind up the 
	testimony, seal the teaching among my disciples," cf. 30:8). Again, it 
    requires both modern assumptions about authorship, as well as ignoring the 
    culture of the ancient world, to conclude that these disciples did nothing 
    but preserve word for word what Isaiah said without allowing the message to 
    be dynamic within their community or applying that message to later events. 
    We know that even in the classic Greek period, students of the Greek 
    philosophers wrote and spoke in the names of their masters, speaking to a 
    new generation and a new time what the master would have spoken had he still 
    been alive (this may also be the case with Paul and the Pastoral Epistles). 
    Again, this suggests that it may be a lack of understanding of the ancient 
    world and our assumptions at work that allows us to even make authorship an 
    issue.             
    4) Some assume that New Testament 
    references to Isaiah speaking or writing certain passages that are quoted in 
    the New Testament are proof that the prophet Isaiah of Jerusalem was the 
    author of all of that material.  Yet, New 
    Testament references to Isaiah refer to the book as part of the tradition of 
    sacred writings by traditional titles and do not intend to present arguments 
    about authorship.             
    There are several dimensions of this aspect. First, as just noted, the idea 
    that the biblical community was as concerned as we are about who wrote what 
    material is an assumption from our modern ways of thinking. To project our 
    concern about authorship into New Testament references to Old Testament material is simply to 
    force the Bible to address issues that it does not address.              
    Second, because of these different perspectives, the New Testament community may not 
    have known any more about the precise author of individual material in the 
    Old Testament than we do. To assume that the biblical writers knew who wrote the 
    material almost always invokes a certain theory of inspiration in which God 
    simply reveals to them such information. While that may be adequate for 
    some, it obviously goes far beyond the evidence we have in the text itself, 
    and again uses theological ideas as the basis for deciding biblical issues.             
    Third, there are several instances where the New Testament writers seem not to have 
    remembered where certain passages were located, or remembered them 
    incorrectly. For example, Mark 1:2 introduces the Old Testament quotation by "as it is 
    written in the prophet Isaiah," but begins by quoting a passage from 
    Malachi. Another example is Matthew 27:9 where the reference is given as 
    Jeremiah, but the passage is actually taken from Zechariah. It is also 
    interesting that there are manuscript variations that give the reference as 
    Isaiah, and some that make the correction to Zechariah (see
	Sacred Words or Words about the Sacred?).             
    All this says that even the references to the locations of Old Testament 
	quotations or allusions 
    are not always precise in the New Testament. That in itself is no problem, since the 
    focus is on the message being communicated rather than precision of 
    citation. That is, unless one is trying to maintain certain views about the 
    nature of Scripture, such as totally inerrancy. Then it presents a problem 
	(see The Modern Inerrancy Debate). 
    If the locations of the texts are not precise, it is only certain assumptions 
    at work that allow the New Testament references to the Old Testament to be adequate for 
    determining authorship of the Old Testament texts.             
    5) A few assume that references to 
    Isaiah throughout Scripture provide proof that he was the author of the 
    material that bears his name. Nowhere in Scripture 
    is there any claim that Isaiah of Jerusalem is the author of the entire book 
    of Isaiah. There is no question that the prophet Isaiah is the 
    focal point of the traditions that carry his name. But again, there are certain assumptions at work that allow us to conclude that he is the single 
    and only person responsible for the entire book.             
    A Different Perspective            
    I would suggest that there is unity 
    and coherence in the book of Isaiah, but that unity is 
    not a historical             
    unity that comes from being written at a single point in history 
    by a single person. The unity of Isaiah is a theological unity             
    rather than a historical one. The unity is the witness of the Faith 
    community to God in the midst of changing historical circumstances. The 
    community was struggling to come to grips with historical events in relation 
    to what they understood about God and his actions in the world. 
    Theologically, the witness of the book of Isaiah is consistent and 
    unrelenting. Central themes can be traced throughout the book even though 
    the historical circumstances have changed. In places, different themes take 
    center stage or the emphasis is different: judgment in the first section of 
    Isaiah, creation theology and grace in the second section, and faithful 
    response to God in the third section. But there is an overall cohesion in 
    the message of the book.             
    This suggests that nothing is lost in understanding a theological 
    unity in the book rather than a historical one, except perhaps certain views 
    of prophecy and the nature of Scripture that do not even originate from the 
    biblical texts themselves. I would even contend that understanding the 
    theological unity and dynamic of the book makes it far more relevant to the 
    modern world, and for most people who live in it, than does seeing the book 
    only as a prediction of the future that is now for us 2,000 years in the 
    past. Rather than making Scripture more valuable, I fear that such a 
    position is preaching to the choir, simply making people who believe the 
    Bible feel good about what they already believe. For others, I fear it 
    removes Scripture from the "real" world in which they live, and therefore 
    removes much chance of its message impacting their lives at the point of 
    their need.             
    Two Communities: The Evidence from the Book Itself            
    Perhaps it would be helpful to examine some of the evidence from within 
    the book itself. I would contend that this is not a matter of faith but a 
    matter of investigation. We may accept the Bible as authoritative Scripture 
    for the church, and yet not make that authority dependent on conjectures, 
    one way or the other, about authorship of any particular book. The authority 
    of the book is not in the historical details of authorship, but in the 
    message about God that the book carries. That is why even though we may have 
    divergent opinions about the issue based on the evidence, it is not a matter 
    to argue in terms of belief or non-belief in the authority of Scripture. And 
    it is certainly not a shibboleth of orthodoxy by which to judge another 
    person’s commitment to God.             
    If we try to lay aside these assumptions and look at the internal 
    evidence of the book itself without trying to fit them into any rationalized 
    scheme about the book, we may be able to highlight how the assumptions tend 
    to ignore or rationalize evidence. And it may allow us to develop a more 
    dynamic view of the book as Scripture within a living community of faith.             
    There are several lines of internal evidence 
    that point to three distinct time periods for the book of Isaiah. 
    It was fashionable in the first part of the 20th century to speak of three 
    Isaiahs, usually labeled First, Second, and Third Isaiah for the three parts of the 
    book. Today, there is less concern in labeling the parts of the book in 
    terms of authorship, and a greater tendency to understand the book in terms 
    of an ongoing dynamic prophetic tradition that can be identified in the three 
    different time periods. In other words, the emphasis has shifted from trying 
    to establish either a single or multiple authors, and moved more to placing 
    the movement of the book within the flow of history as the community came to 
    terms with events in relation to the Isaiah traditions entrusted to them. 
    The power of the book is that it reflects a community of faith’s struggle to 
    be faithful amid the most tumultuous period of Old Testament History.             
    Isaiah of Jerusalem’s prophetic ministry spanned roughly a 40 year period 
    from around 740 BC to about 700 BC (See Chart 
    of Israelite Prophets) in the Southern Kingdom of Judah. This would 
    place him active during the reigns of 
    Jotham, Ahaz, and 
    Hezekiah, the period of Assyrian dominance. Assyria rose as a world 
    power in 745 BC, invaded and destroyed the Northern Kingdom of Israel in 721 
    BC, subjugated the Southern Kingdom during the reign of Ahaz, and nearly 
    destroyed it in 701 during the reign of Hezekiah. Isaiah’s entire ministry 
    focused on calling the people to repentance, especially the weak Jotham and 
    the apostate Ahaz, trying to avert disaster at the hands of the Assyrians, 
    and later encouraging Hezekiah in his attempts at reform and rebellion 
    against Assyria. While the Assyrians ruled over Judah during much of this 
    time, exacting heavy tribute from the people, they never managed to conquer 
    the city of Jerusalem even though they nearly succeeded in 701. According to 
    the biblical witness, God intervened and saved the city from the Assyrians (Isa 
    37:36-38, 2 Kings 19:35-37).             
    It is that historical light that some of the evidence within the book of 
    Isaiah needs to be examined.             
    1) There are numerous references 
    throughout the book to the Babylonians (or Chaldeans). Babylon would not 
    emerge as a world power until 612 when they captured the Assyrian capital of 
    Nineveh, and would not stand alone until 609 when they wiped out the 
    remnants of the Assyrian army and defeated the Egyptian pharaoh who was 
    trying to intervene. In the time of Isaiah of Jerusalem, the enemy was the 
    Assyrians and the Babylonians were not even on the stage of history yet. 
    This suggests that the ongoing community of faith who valued Isaiah’s 
    message in the time of the Assyrians simply took that message and reapplied 
    what he had to say in the context of their own current enemy, the 
    Babylonians.             
    There are references to the Babylonians in the first part of Isaiah 
    (1-40), largely in the typical oracles against foreign nations (chs 13, 14, 
    21) and in chapter 39, which serves as a transition between the two eras and 
    parts of the book. Yet, the Assyrians do not appear again the book past the 
    account of their failure to take Jerusalem in 701 (38:6), except for a 
    single occurrence that is clearly a reference to a long past time (52:4). 
    Beginning with chapter 40 the Babylonians, and their eventual downfall to 
    the Persians are clearly the main topic (for example, ch 44:28, 45:1, 47, 48:14-22, 
    etc.).              
    This likewise suggests that Isaiah 1-39 generally dates to the Assyrian 
    period between 740 and 600 BC, while chapter 40 following dates at least to 
    the Babylonian era, sometime after 612. The earlier material was 
    interspersed by the later community with references to their own enemies, 
    the Babylonians, as a way to apply the earlier material theologically to 
    their own historical circumstances. But the later material does not include 
    references to the Assyrians since they were long gone, had been judged by 
    God and history, and posed no concern to the later Israelites who were 
    preoccupied with the Babylonians and Persians.             
    2) There are several references to 
    the temple in Jerusalem being destroyed as if it were an event some time 
    removed in the past (44:26-28, 52:8-9, possibly 51:3). This happened in 586 
    BC as the Babylonians             
    captured and destroyed the temple along with Jerusalem itself. While some 
    want to argue that this is simply predictive prophecy, that perspective 
    again invokes certain assumptions that stand outside the biblical text 
    itself. The most reasonable interpretation of those passages apart from that 
    assumption is that they come from a time after the temple was destroyed. 
    This is especially true of those passages that anticipate        
    rebuilding             
    the temple and the city (44:26).             
    3) Along the same line, there are 
    numerous references to the devastation of the land and of people carried 
    captive to Babylon (40:1-2, 42:22-24, 
    43:14, 48:20, 51:17, 52:1-2, etc.). These deportations happened in 598 and 
    again in 586, and perhaps an earlier deportation in 605 when the Babylonians 
    first entered the land and put Judah under Babylonian control. While there 
    were deportations by the Assyrians as they annihilated the Northern Kingdom 
    of Israel, there were no large scale deportations from the Southern Kingdom 
    of Judah. All of the references to exile of Israelites in the second section 
    of the book (and at least one in the first, 14:2) are in relation to Babylon 
    (for example, 49:24, 52:2, 61:1, etc.).             
    4) There are several general 
    references to a new leader emerging in Mesopotamia (41:2-3, 25), and two 
    specific references that name Cyrus the Persian as the instrument of 
    Israel’s deliverance from Babylon (44:28-45:3). Again, by using assumptions 
    about the nature of prophecy and Scripture, many conclude that this is 
    simply Isaiah of Jerusalem precisely predicting the future. However, apart 
    from those assumptions, and in line with earlier material in the book of 
    Isaiah, this appears to be a prophetic interpretation of the meaning of 
    unfolding historical events in light of God’s purposes at work in that 
    history. That is exactly how Isaiah of Jerusalem responded to the 
    Assyrian crisis 100 years earlier. In other words, it is more likely 
    that a later community using the Isaiah traditions interpreted the change of 
    power in the East as God’s work in the world to bring the exiles home. Cyrus 
    the Persian came to power in 539 BC and issued the edict that allowed the 
    Israelites to return home in 538. This would place the section of Isaiah 
    following chapter 40 around 540-539.             
    5) Finally, there is clearly a 
    radical shift in tone and theological outlook in the book at chapter 40. The 
    first 39 chapters focus on the failure of the people to be faithful to God, 
    the stubborn recalcitrance of their leaders, and the near total failure of 
    the nation to live up to its calling as God’s people. Even Hezekiah, who is 
    portrayed as a righteous leader, fails in several ways, including bragging 
    of his wealth, a move that the book of Isaiah attributes as a cause of the 
    later Babylonian invasion.              
    However, beginning in chapter 40, as the first words of "Comfort, 
    comfort" in the section indicate, the perspective is hope for the future and 
    encouragement. There is a sense of a recent great catastrophe that has 
    devastated the land and people, and yet the book holds out great hope for 
    the future. It is clear that new winds are blowing that portend a change in 
    fortune, brought by the grace of God. Again, many want this to be prediction 
    of the future. But in the context of the book, the sense of the text is that 
    these are currently unfolding events that draw forth profound joy and 
    anticipation from a context of near despair. It is clear that the arrogance 
    of the people in Isaiah’s time would not even allow them to conceptualize a 
    problem or foresee such a disaster, let alone get very excited about what 
    lay on the other side. The nearly unbridled hope and expectation of chapter 
    40 ff. is simply not the message needed in 700 BC.             
    There are other bits of evidence , but this seems sufficient to establish 
    that there are plausible reasons within the biblical material itself to see 
    chapters 1-39 in the Assyrian era of the late 8th century BC, while the 
    material beginning with chapter 40 is from a later period around the middle 
    of the 6th century BC.             
                
    The evidence for a third time period for the book of Isaiah is not as 
    direct and the demarcation between the second and third sections of the book 
    are not as pronounced, but for many is just as convincing. This conclusion 
    depends on several lines of evidence:   1) an analysis of the 
    content and theological perspective of the latter part of the book (chs. 
    56-66) compared to what we know of unfolding history in the period following 
    540 BC; 2)  the close connection with the theological perspective of 
    other books from the same period (Malachi, Ezra, Nehemiah), and 3) literary 
    features that mark a shift between chapter 55 and 56. Since a careful 
    analysis of all these is beyond the scope of this article, the perspectives 
    will only be summarized here.             
    1) As already mentioned, the 
    pronounced shift between the first and second sections of the book is 
    striking in terms of the tone and theological perspective of the two 
    sections. The first section (1-39) is largely prophetic judgement speeches 
    and calls to repentance, with the tone set by 1:10-20. The second section 
    (40-55) is almost entirely promises of restoration and the eager 
    anticipation of a new golden age brought by God’s reestablishment of the 
    people in the land, with the tone set by 40:1-11.              
    The third section, however, returns to a much darker and more pessimistic 
    perspective that again points out the people’s failure to respond adequately 
    to God. There are again problems with idolatry (57:4-13), injustice 
    (59:1-8), and superficial religion (58:13-14). Yet, the mood that is 
    addressed by this section of the book is fairly obviously one of 
    indifference and apathy in which the people believe that God will not or 
    cannot act to improve their situation (for example, 56:9-12,58, 59:9-11). 
    This reveals that the primary problem is not really rampant and aggressive 
    Ba’al worship even though it was still practiced, or injustice flowing from 
    prosperity and self-confidence as had been the case earlier in the book. 
    Here the problems in those areas arise because the people have concluded 
    that it makes no difference what they do, because God does not see or care, 
    that he will do nothing to intervene.             
    This fits very closely with what we know of the period following the 
    actual return from exile (see The Persian Period 
    and Return from Exile, especially 
    Persian Rule and Return From Exile). Even though the return began in 
    538, the prophet Haggai scolded the people 20 years later for not being 
    concerned about rebuilding the temple or the city. Nearly 100 years later, 
    Nehemiah, appointed governor of the area by the king of Persia, was still 
    trying to get the city walls rebuilt (Neh 3-6). And Ezra about the same time 
    was still trying to get the people to recover some sense of who they are as 
    God’s people (Neh 8).              
    History unfolded in quite a different way than the community of the 
    middle section of Isaiah envisioned it. There was so much elation at the 
    prospect of a return from exile and the restoration of the nation that the 
    rhetoric sometimes became rather grandiose. There is no question that some 
    of the pronouncements in that second section are highly metaphorical ways of 
    making the theological point that God was at work in the rise of the Persian 
    empire and the end of Babylon. Yet, many took the exaggerated language as a 
    historical program of how the restoration would unfold. So when the grand 
    visions did not unfold in history exactly the way the people thought they 
    should, they became discouraged.             
    They had much to be discouraged about in that 100 years following the 
    return. A quick survey of the books of Ezra and Nehemiah will reveal how 
    difficult life was in Israel between 538 and 450. The people were barely 
    surviving. Very few had actually returned from Babylon. Most had simply 
    stayed there. Since most of them had been born there,  for all 
    practical purposes they were Babylonians.  Life had been good in 
    Babylon. They were not kept as slaves, but allowed to become part of 
    Babylonian culture. As such, they had prospered.             
    Most of those who had returned were priests, probably not the best 
    group to rebuild a totally devastated land, which likely explains why so 
    little rebuilding was actually carried out for 100 years. And even when the 
    temple was rebuilt under Zerubbabel and Ezra in 520, it was not the same 
    beautiful temple that Solomon had built. They likely only restacked the 
    stones from the destroyed walls of the old building. Ezra 3:12 tells us that 
    some of those who were still alive who had seen and remembered Solomon’s 
    temple wept when they saw the foundations laid for the new building, 
    apparently because they knew it would only be a crude imitation of that 
    earlier temple.             
    The people had no protection, since the city walls had been leveled. They 
    were constantly at risk from marauding bandits and rival tribes (Ezra 4; cf. 
    Neh 2:10). There was even opposition from the Israelites who had been 
    allowed to remain in the land. Those who returned that were not priests 
    wanted to reclaim ancestral lands that had been taken over by those who had 
    remained.  Yet they had been on that land for 70 years, and saw the 
    claims as a threat to their own security.  Since the olive trees had 
    been cut and the vineyards destroyed, food was in short supply (it takes 
    many years for an olive tree to produce fruit after it is planted).             
    So, many simply concluded that the promises were false and that God was 
    not really much of a god after all. This allowed apathy, the idea that God 
    is powerless and does not care what they do, to set in. There are even 
    traces of a developing cynicism (cf. 56:12). It is this disillusionment and 
    despair of things ever getting any better that is reflected in the third 
    section of Isaiah.             
    2) Most of the perspectives above can 
    be easily seen in Ezra and Nehemiah, as well as in the prophetic books of 
    Haggai and Zechariah. But the most obvious parallel is found in the book of 
    Malachi. The main thrust of this prophet’s message is his challenge of the 
    indifference and apathy of the people (3:14): "You have said, ‘It is of no 
    purpose to serve God. What do we profit by keeping his command or by going 
    about as mourners before the Lord of hosts?’" This entire book is directed 
    at the attitudes of people and priests alike who have concluded that God no 
    longer cares for them ("How have you loved us?" 1:2). The book of Malachi, 
    is usually dated between 500 and 450 BC, while Haggai and Zechariah are 
    dated only slightly earlier, around 520-515 (see 
    Israelite Prophets Date Chart). This is likewise about the time of the 
    work of Ezra and Nehemiah and the events that the books that carry their 
    names recount.             
    All this says that the theological perspectives of the third section of 
    Isaiah, and the concerns they address, are the same concerns faced by the 
    community of returned exiles in the period from about 540-450 BC. These same 
    perspectives appear in the prophetic writings from this period, and fit with 
    what we know is going on historically from the books of Ezra and Nehemiah. 
    This simply suggests that this third section of Isaiah is far more likely to 
    be contemporaneous with these prophets in this time period than with Isaiah 
    of Jerusalem in 700 BC. This would place a time frame for this third section 
    of the book somewhere between 515 and 500 BC.             
    3) While the literary features of the 
    book cannot help us much with a precise time period, they can confirm that 
    there is some type of shift in the book between chapters 55 and 56. We have 
    already noted the clear transition between chapters 39 and 40. We might 
    likewise expect some literary clue to divide these chapters if, indeed, they 
    should be seen to address different periods of history.             
    The end of chapter 55 does, indeed, seem to provide just such a 
    conclusion and transition. In fact, the last three chapters, 54-55, serve to 
    bring this section to a climax in fairly typical prophetic fashion. 
    Following the strongly future dimension of the servant passage in 52-53 
    (however one might interpret the servant), there follows immediately the 
    Song of Assurance (54), picking up the familiar Old Testament image of the 
    joy of a barren woman who is now promised children (54:1). This chapter is 
    clearly a celebration of God’s grace in the restoration from exile. The 
    final chapter of this section is a call for the people to respond to that 
    grace, a call to change and a new future based on God’s gracious act of 
    restoration (55:6-7):             
    	Seek the LORD while he may be found, 
      call upon him while he is near; let the wicked forsake his way, and the 
      unrighteous man his thoughts; let him return to the LORD, that he may have 
      mercy on him, and to our God, for he will abundantly pardon.             
    The same feature of a climactic call to repentance can be seen in the 
    conclusion to the book of Hosea (14). Verses 12-13 of chapter 55 are a 
    hymnic conclusion to the chapter and to the second section of the book.             
    Verses 8-11 of chapter 55 tie the second section to this third section of 
    the book in message and theme. The key idea is the validity and reliability 
    of God's word. The idea of God speaking and the reliability of what God says 
    is a key ingredient of the second section of Isaiah, especially chapter 40, 
    particularly in verses 6-8. The issue in that second section of the book is 
    the promise of God's new action in history that would effect the restoration 
    of Israel back to its land. The word of Yahweh is sure, even if 
    inscrutable. The images of rain and growing seed illustrate the wonder and 
    mystery of God's ways. The word here is not just the content of what 
    is said; it is the agency, the instrument through which something is 
    effected, in this case God himself. The focus here is on Yahweh's 
    faithfulness and mercy to restore his people, as well as his will to do so.             
    However, God's word is not automatic, it does not work on its own apart 
    from God or disassociated from the people’s response to it (55:6-9). God's 
    promise may be accepted or rejected. Disobedience or failure to accept God's 
    promise does not necessarily invalidate the promise. But the question is 
    clearly left in the air by the call to respond in chapter 55 whether failure 
    to respond faithfully to the promise might not somehow hinder or endanger 
    the promises of that second section. This becomes the key connective to the 
    third section of the book. As noted, the issue facing the community 
    reflected in this third section is the disillusionment of the people with 
    their historical circumstances. The lack of the glorious kingdom promised by 
    earlier prophets precipitated a severe crisis of faith for this community. 
    It is this crisis that this third section addresses as the book attempts to 
    revalidate the promises and rebuild a hope for the future that has almost 
    been lost.             
    Like the previous two sections, the theme of this entire third section of 
    the book is introduced in 56:1: "Keep righteousness and do justice for soon 
    my deliverance will come." This reveals that the problem is in the delay of 
    the promises, corresponding closely to the New Testament problem: "where is the promise 
    of His coming?" It also reveals that the problem involves a failure on the 
    part of the community, just as in the corresponding prophecy of Malachi. 
    Theologically, the call is for the people to be faithful to God and live as 
    God's people in the world even when there is no direct evidence that God is 
    there.             
    Summary            
    This evidence leads to two conclusions. First, 
    it seems entirely likely from the book itself, that the Isaiah traditions 
    stretch over a span of time from the era of Isaiah of Jerusalem in the 
    middle eighth century BC to the post exilic era in the early fifth century 
    BC. The three sections of the book sort out into three distinct time periods 
    within the life of the community during that period.             
    The first section, chapters 1-39, comes from the 
    Assyrian period and is directly associated with the ministry of Isaiah of 
    Jerusalem from 740 to 700 BC. That does not mean that all 
    material within those chapters dates from that period, however, since there 
    are clearly some later additions to this collection from the Babylonian era. 
    But it does establish Isaiah of Jerusalem as the founder of the Isaiah 
    traditions.             
    The second section of the book, 40-55, comes 
    from the late exilic period as the empire of Babylon was coming 
    to an end and the Persian empire was emerging as the new ruler of the Middle 
    East. If we take the edict of Cyrus in 538 as a benchmark for this era, this 
    section of the book dates to about 540-539 BC.             
    The third section of the book, 56-66, reflects 
    the crisis of faith precipitated by unfulfilled or delayed prophecy, 
    a situation that we know from Haggai, Zechariah, and Malachi prevailed 
    between 520 and 450 BC. If we use the time of Haggai around 520 as benchmark 
    for this era, this third section of Isaiah probably comes  
    from the period 515-500, with the possibility that it may extend 
    as late as 450.             
    As suggested earlier, the unity of the book of Isaiah is not to be found 
    on the level of history or authorship. Its unity lies on the level of its 
    theological message about God and how the people responded, and should 
    respond, to his work in the world.             
    Second, seen in this light, there is 
    really nothing in the book itself that directly addresses the idea of 
    predictive prophecy, either for or against. It is simply not what lies at 
    the heart of the book. This means on the one hand, it is probably a mistake 
    to use the book as any kind of proof text to support the authority of 
    Scripture based on the correspondence of prediction with events that 
    happened hundreds of years later. On the other hand, seeing the book as the 
    unfolding witness to God’s work in the world provides no direct proof that 
    there is no predictive prophecy. In other words, the whole issue of 
    predictive prophecy must be dealt with on other grounds than a study of the 
    book of Isaiah. That issue is much more an problem that arises from certain 
    theological assertions than it does from most biblical texts. There are 
    other texts that address the issue more directly (see 
    Ezekiel and the Oracles Against Tyre). But at least in the way that the 
    Isaiah texts have been used, the unity and authorship of Isaiah are not very 
    good weapons with which to fight that battle.
