Book of Isaiah

Judah and Jerusalem stand at the center of Isaiah’s opening declaration, which identifies the work as the vision of Isaiah son of Amoz during the reigns of Uzziah, Jotham, Ahaz, and Hezekiah, kings of Judah.[7] The book belongs to Nevi’im, the Prophets, the second division of the Hebrew canon; the Hebrew name Isaiah, or Yeshayahu, means “Salvation of YHWH.”[3] Isaiah son of Amoz also appears outside the book in II Kings and II Chronicles.[3] The work is likewise counted among the major prophetic writings of the Old Testament.[2]

The book’s central concerns extend beyond predictions of political events to the character of society and the relationship between religious conduct and justice.[3] Its early chapters condemn unfaithfulness, corruption, religious hypocrisy, and the abuse of vulnerable people, while presenting God as the “Holy One of Israel,” sovereign over all nations.[2] Judgment is accompanied by the promise of a future for those who rely on God, and Jerusalem’s corruption is set against the prospect of its restoration.[3][7] Later chapters develop consolation, return to the homeland, and redemption as major themes.[1][6]

Isaiah is not a continuous narrative or a single uniform literary composition: it contains prophetic oracles from different periods and an extensive range of genres.[2] Most of its material is poetry, while chapters 36–39 contain substantial prose narrative.[2] The poems range from short, proverb-like sayings to longer compositions and include lyric, hymn, allegory, parable, satire, lament, psalm, prayer, and thanksgiving.[2] The book therefore brings together direct accusation, political counsel, prayer, historical storytelling, and visions of restoration rather than presenting its message in one literary form.[2]

A common broad outline distinguishes chapters 1–39, chapters 40–55, and chapters 56–66, conventionally called First Isaiah, Deutero-Isaiah or Second Isaiah, and Trito-Isaiah or Third Isaiah.[2][8] A four-part outline separates chapters 36–39 as a historical appendix, producing divisions at chapters 1–35, 36–39, 40–55, and 56–66.[2] These divisions distinguish the material concerning Isaiah and the Assyrian crisis, the historical narratives about Hezekiah, the promises of deliverance from Babylon, and the concerns of the restored community.[2][8]

Assyrian expansion forms the principal political setting of the book’s early material, which begins against the backdrop of the First Temple period and Israel’s decline.[1][2] Isaiah’s prophetic activity is associated with the death of Uzziah and the reigns of the Judean kings named in the superscription.[3][9] No activity is recorded after Sennacherib’s invasion of Judah in 701 BCE.[2] Jerusalem’s worship and Zion traditions shaped his understanding of God’s sovereignty and his insistence that Judah’s security depended on divine support rather than alliances.[3]

During the Syro-Ephraimite crisis, Pekah of Israel and Rezin of Damascus sought to resist Assyria, while Ahaz of Judah refused to join them.[3] The attack on Judah is placed in 735–734 BCE.[2] Isaiah urged Ahaz to remain calm and confident rather than fear the threat from Aram and Israel, and opposed reliance on Assyria.[3][9] Ahaz nevertheless appealed to Tiglath-Pileser III for help and paid tribute, obtaining temporary protection at the expense of Judah’s independence and exposing it to danger from the power it had enlisted.[3]

The regional consequences of Assyrian expansion included the fall of Damascus in 732 BCE and the destruction of Samaria and the Northern Kingdom in 722 BCE.[2] Ashdod fell in 711 BCE.[2] During a revolt led by Ashdod, Isaiah undertook the symbolic action described in chapter 20, going barefoot and without clothing for three years.[9] The act warned of the consequences of revolt against Assyria and reliance on Egypt.[9] His political counsel thus addressed both the danger of submission to foreign protection and the danger of resistance built on confidence in another foreign ally.[3][9]

Under Hezekiah, Judah revolted against Assyria, and Sennacherib devastated the countryside and besieged Jerusalem in 701 BCE.[2] Isaiah warned against dependence on Egyptian assistance, encouraged Hezekiah not to surrender, and predicted that Jerusalem would not be taken.[3] The biblical account explains the lifting of the siege through a divine visitation that devastated Sennacherib’s camp.[3] Isaiah’s direct access to Ahaz, familiarity with a royal chamberlain, and advisory role under Hezekiah have also prompted the suggestion that he held a court position, possibly as a scribe.[9]

The setting of chapters 40–55 is the sixth-century-BCE Babylonian Exile, with Babylon rather than Assyria occupying the position of the power from which deliverance is promised.[2][8] These chapters contain oracles, songs, and discourses looking toward Babylon’s destruction and the exiles’ return to their homeland.[2][8] Their historical horizon includes Cyrus of Persia, named as the ruler raised up to free the exiles.[2] The later years of exile and the movement toward return are associated with approximately 545–538 BCE, when Cyrus conquered Babylonia and decreed that Jews could return home.[8]

The exilic message addresses a people marked by the destruction of Judah and Jerusalem, displacement, despair, and fear that God had abandoned them.[3] Against that experience, it presents God as directing history and promises Babylon’s fall, release from exile, return to Zion, rebuilding of the Temple, and the ingathering of dispersed Israelites.[3] Restoration is connected to the Zion and Davidic traditions and presented as the realization of purposes articulated earlier in the book.[8]

Chapters 56–66 address the restored community in Judah, including the rebuilding of Jerusalem and the Temple, tensions among the returning population, and the renewal of justice and worship.[2] Their social and religious setting is related to that of Ezra and Nehemiah and the post-exilic prophets Haggai, Zechariah, and Malachi.[2] The final chapters give particular attention to the community’s religious and cultic concerns.[6][2] Across these settings, the book follows Judah and Jerusalem from imperial pressure through exile to the challenges of restoration.[1][2]

Isaiah 1 opens with an accusation that Israel has rebelled against and forsaken God, then turns to demands for concrete ethical action: cease wrongdoing, seek justice, aid the wronged, and defend the rights of the orphan and widow.[7] Its condemnation of corrupt rulers is paired with a promise that Jerusalem will again be called a “City of Righteousness, Faithful City.”[7] The chapter uses courtroom language to charge Israel with wrongdoing and announce Zion’s eventual redemption and restoration.[7] Its movement between complaint and hope establishes the connection between Jerusalem’s moral condition and its promised future.[7]

The denunciations elsewhere in the book identify particular abuses rather than treating injustice only as an abstraction.[3] They include bribery, denial of justice to the innocent, neglect of orphans, seizure of poor people’s land, and luxury financed by the spoils taken from them.[3] Isaiah does not reject Temple sacrifice in itself; he condemns offerings from people whose hands are “full of blood” and makes justice and care for the oppressed essential to religious conduct.[3] The criticism of meaningless worship therefore accompanies, rather than replaces, the book’s concern with the proper religious life of Judah.[3][2]

Isaiah 1:16–20 joins complaint to an invitation to repentance and ethical action.[7] Such direct calls to repentance are relatively rare in Isaiah compared with other prophetic books, and they do not appear from chapter 6 through 31:6.[7] The prophetic teaching in that span has consequently been understood as explaining Judah’s circumstances rather than repeatedly urging its people to change their behavior.[7] Elsewhere, repentance, justice, and trust in God are linked to the possibility of stability and restoration.[2]

Chapter 6 presents Isaiah’s vision in the year King Uzziah died, with God enthroned in the Temple and seraphs proclaiming divine holiness.[10] Their proclamation reads, “Holy, holy, holy! GOD of Hosts—Whose presence fills all the earth!”[10] A seraph touches Isaiah’s lips with a live coal from the altar before he hears the question, “Whom shall I send? Who will go for us?”[10] Isaiah answers, “Here am I; send me.”[10] The scene brings together the Temple setting, God’s holiness, and Isaiah’s acceptance of the prophetic mission.[10]

The early chapters repeatedly oppose confidence in human political schemes to reliance on God.[3] Isaiah’s counsel against alliances is grounded in the conviction that God, rather than the military arrangements of Judah’s rulers, governs the nation’s future.[3] This emphasis stands alongside the survival of a faithful remnant, Jerusalem’s future religious importance, and hope for a ruler from the root of Jesse who establishes justice and peace.[3] The message therefore includes both warnings of punishment for unfaithfulness and a positive vision of righteous government and restored communal life.[3][2]

Within chapters 1–35, chapters 1–12 principally address Judah and Jerusalem, while chapters 13–23 gather prophecies concerning other nations.[2] The more precise range Isaiah 13:1–23:18 encompasses peoples beyond Israel and Judah.[7] Chapters 24–27 and 34–35 contain apocalyptic material concerned with judgment on the nations, divine victory, and salvation, while chapters 28–33 include oracles of judgment and hope.[2] The oracles of chapters 1–35 are not arranged consistently in chronological order.[2]

The international scope of the book includes a vision of reconciliation as well as pronouncements of judgment.[7] Isaiah 19:24–25 depicts Israel, Egypt, and Assyria as partners in a blessing on earth, with all three named in the divine blessing.[7] Isaiah 2:4 describes God judging among nations and arbitrating for many peoples, who transform their weapons into agricultural tools.[4] Its declaration that “They shall beat their swords into plowshares” is followed by spears becoming pruning hooks and nations no longer taking up swords against one another or learning war.[4]

Chapters 36–39 bring the Assyrian threat under Hezekiah into a sequence combining narrative, prophecy, poetry, and biographical details.[2] The material substantially parallels 2 Kings 18–20 and includes Hezekiah’s illness and recovery as well as a prediction of Babylonian captivity.[2] By including both the Assyrian crisis and a forecast of captivity under Babylon, these chapters place the experience of Hezekiah alongside the later disaster addressed by the book’s promises of consolation.[2]

Isaiah 40 opens with the repeated instruction, “Comfort, oh comfort My people,” and announces that Jerusalem’s term of service is over.[5] The following verses picture a road cleared through the wilderness, valleys raised, and hills made low, before declaring that God’s presence will appear and all flesh will behold it.[5] Chapters 40–55 shift the prevailing emphasis from warnings of punishment to consolation, forgiveness, and promised restoration.[2] Their poems speak both to the exiles in Babylon and to the coming renewal of Zion.[2]

Four passages within this material are commonly designated the servant-of-Yahweh songs: Isaiah 42:1–4, 49:1–6, 50:4–9, and 52:13–53:12.[3] These form a notable group within the larger collection of exilic oracles, songs, and discourses.[3][2] The later chapters also develop teachings about God’s uniqueness and creation, Israel’s destiny, and the social and religious responsibilities of the restored community.[6] Isaiah 56:6–7 includes foreigners in worship at the Temple and describes God’s house as “a house of prayer for all peoples.”[6]

Consolation and redemption are sufficiently prominent in Jewish reception of Isaiah that a traditional explanation of the prophetic books’ order places it after Jeremiah and Ezekiel as the culmination of a movement from destruction toward consolation.[7] Jewish interpreters have used Isaiah to understand Jerusalem’s restoration, while Christian interpreters have used it to understand the revelation of the Messiah.[7] Its recurring hopes include the return to Zion, the ingathering of dispersed Israelites, the rebuilding of the Temple, and Jerusalem’s future religious importance.[3] These themes link the book’s treatment of Jewish national restoration with its visions of justice and peace among nations.[3]

The manuscript record includes two Isaiah scrolls, one complete and one almost complete, discovered among the Qumran Dead Sea Scrolls in 1947, together with fragments of the book.[2] Comparison with the Masoretic Text and the Septuagint reveals textual variants while showing that the overall text has been well preserved.[2] The Great Isaiah Scroll, designated 1QIsaᵃ, contains all 66 chapters and dates to approximately 125 BCE on radiocarbon and paleographic evidence.[11] It consists of 17 stitched parchment sheets, with the text arranged in 54 columns.[11][12]

The Great Isaiah Scroll was discovered near Qumran in 1947 after a Bedouin shepherd entered a cave while searching for a stray goat.[11] Israel acquired the scroll in a secret operation in 1954, and in 1955 the government decided to establish the Shrine of the Book to preserve it.[13] The original was displayed when the Israel Museum opened in 1965; it is normally kept under controlled conditions, with a facsimile displayed in the Shrine’s central dome.[11]

The scroll’s wording largely mirrors the accepted Jewish biblical text, with differences that include spelling and individual words.[11] One reported comparison places its agreement with the Masoretic Text at approximately 95–98 percent and characterizes the differences as largely spelling or minor grammatical variations.[11] Its preservation thus supplies an ancient manuscript witness to the book while also providing material for the study of textual differences.[2][11]

A scholarly edition of the Great Isaiah Scroll was prepared from the leather manuscript itself, housed in the Israel Museum’s Shrine of the Book in Jerusalem, and from three sets of photographs.[14] Transcriptions were checked against enhanced computer images of John C. Trever’s negatives to clarify difficult characters.[14] The edition sought the greatest possible accuracy and indicated most emendations made by different scribal hands, although it did not record every technical detail of the corrections.[14] This work combined direct inspection of the ancient object with photographic and computer-assisted examination.[14]

In 2026, the Israel Museum displayed the Great Isaiah Scroll in full for the first full public viewing since 1968.[11] Conservation requirements limited admission to 25 visitors at a time and ten minutes in a temperature-controlled gallery.[11] Conservation staff also described the need to control humidity, temperature, and light during the scroll’s movement and exhibition.[12] The exhibition brought the original manuscript before the public while retaining restrictions required for its preservation.[11][12]

The relationship between the book’s attribution to Isaiah son of Amoz and its proposed stages of composition is a major issue in its interpretation.[3] Rabbinic tradition generally treated it as the work of one prophet, while Bava Batra 15a attributed its writing to Hezekiah and his colleagues.[3] Abraham ibn Ezra questioned whether chapters 40–66 were written by Isaiah ben Amoz because they reflect later historical circumstances.[3] Modern critical scholarship generally distinguishes material associated with the eighth-century prophet in chapters 1–39 from later material addressing exile and restoration, although some scholars defend unified authorship.[3][2]

In the multiple-contributor model, Isaiah’s disciples preserved and supplemented his oracles, later prophetic writers adapted the message to exile and restoration, and editors assembled the collections.[2] Chapters 40–55 are associated with an anonymous exilic prophet, while chapters 56–66 are associated with one or more later contributors.[3][2] The number of contributors and the boundaries of their work remain unsettled, including whether chapters 56–66 should be separated from chapters 40–55.[3][8] Proposed literary histories span a lengthy process from the eighth through third centuries BCE, with one reconstruction placing the gathering of the collections between 400 and 200 BCE and some apocalyptic material around 300 BCE.[2]

The identity of the servant in the servant songs is another substantial interpretive question.[3] Readings include Israel collectively, an ideal or future Israel, a prophet, or another individual figure, and Jewish and Christian interpretations have varied across generations.[3] Many scholars identify the servant with Israel, while other interpretations understand an idealized individual who represents the community.[3] More generally, the complexity of Isaiah’s Hebrew poetry, its range of language, and uncertainty about the boundaries of individual poems create difficulties for translation and interpretation.[2]
