BIBL 322 — The Book of Isaiah
BIBL 322 reads the book of Isaiah straight through, by the shape the book gives itself. After an opening that sets Isaiah in the eighth-century Assyrian crisis and reads the prophet's call vision, the book falls into three great movements: Judgment and the Assyrian Crisis (chapters 1–39), where the Holy One arraigns Judah and the nations and yet promises a coming king; Comfort and the New Exodus (chapters 40–55), where the incomparable Creator-Redeemer comforts the exiles and the Servant of the LORD bears their sins; and the New Heavens and the New Earth (chapters 56–66), where a restored and widened Zion looks to a new creation. A closing module reads Isaiah in the New Testament — the book the apostles drew on more than any other. The course is organized by Isaiah's own movement rather than by theme, and its signature skill is reading every text through the Holy One of Israel: catching where God's holiness stands at the center of a passage, watching that holiness both judge what is proud and unclean and redeem what it has judged, and holding the two together as the work of the one Holy One. Isaiah also raises the hardest questions in the Old Testament, and each is held in the three-register, every-side-fairly discipline: the unity and authorship of the book (one Isaiah or several), the identity of the Servant who suffers in chapter 53, the sign of Immanuel, the messianic readings of the coming king, and — with the greatest care — how the New Testament reads Isaiah without erasing its plain sense and without supersessionism. Every reading works from English (the World English Bible) through the platform's scripture-reference blocks, with a Hebrew study popover behind any word for readers who want the original; no Hebrew is assumed. The companion course BIBL 304 reads Isaiah alongside Jeremiah, Ezekiel, Daniel, and the Book of the Twelve as part of a survey of the prophets; this course reads Isaiah on its own terms, chapter by chapter, the whole way through.

- Trace how the New Testament reads Isaiah ("the fifth Gospel") in register, and synthesize the book by reading the Holy Way of Isaiah 35
The Holy One of Israel
Isaiah son of Amoz prophesied in eighth-century Judah while Assyria rose in the east and the northern kingdom fell. This opening module sets that world, lays out the three-part shape of the book, and weighs in register the question that runs beneath all of it: whether one Isaiah or several stand behind the sixty-six chapters. It then hands the reader the lens the whole course practices, reading every text through the Holy One of Israel, and reads the call vision of chapter 6, where the thrice-holy God both undoes Isaiah and cleanses him.
The Indictment and the Coming King
Isaiah 1 through 12 opens with a courtroom: the Holy One arraigns a rebellious Judah, sings the bitter song of the vineyard that yielded only wild grapes, and exposes the pride that the Day of the LORD will bring low. Yet judgment does not have the last word. In the Syro-Ephraimite crisis the sign of Immanuel is given to a faithless king, and out of the felled house of David rise the child called Prince of Peace and the Spirit-anointed shoot from the stump of Jesse, on whose holy mountain the wolf lives with the lamb. The sign of Immanuel and the messianic readings of the coming king are each held in register, the plain sense and the New Testament reading kept distinct.
The Nations and the Day of the LORD
The oracles of chapters 13 through 23 turn outward to Babylon, Moab, Damascus, Egypt, and Tyre, declaring that the Holy One rules the whole sweep of history and that no nation's pride stands before him. The taunt over the fallen king and the burdens of the peoples give way in chapters 24 through 27 to a cosmic vision, the earth itself laid waste under the Day of the LORD. There, on the mountain, the LORD spreads a feast for all peoples and swallows up death forever, and the same holiness that judged the nations gathers a people to itself.
Woes, Trust, and the Assyrian Deliverance
A series of woes falls across chapters 28 through 33 on leaders who scoff at the prophet and on a people who run down to Egypt for help rather than look to the Holy One of Israel, while the LORD lays in Zion a precious cornerstone and calls them to find their strength in quietness and trust. The crisis comes to a head when Sennacherib's army surrounds Jerusalem and the Rabshakeh mocks Hezekiah's confidence, until the king's prayer is answered and the city is delivered. Chapter 39 then turns the book on its hinge: envoys from Babylon arrive, and the prophet foretells the exile that the second half of Isaiah will address.
Comfort and the Incomparable God
At chapter 40 the tone changes: "Comfort, comfort my people," a voice cries in the wilderness, and the grass withers while the word of God stands forever. These chapters set the incomparable Creator who measured the waters in his hand against the idols that are nothing, place the trial of the nations beside the first Servant Song, and reach their scandal when the LORD names Cyrus, a pagan Persian king, his shepherd and his anointed. The shift of setting at chapter 40 is where the unity-and-authorship question returns, weighed there again in register with no verdict pressed.
The Servant of the LORD
Chapters 49 through 55 follow the Servant of the LORD to the heart of the book. The second and third Servant Songs send him as a light to the nations and show him giving his back to those who beat him, and then chapter 53 reads the fourth song slowly, the one despised and rejected who bears the sickness of many and is pierced for their transgressions. Who this Servant is, whether corporate Israel, a faithful remnant, a prophet, the Davidic Messiah, or the figure the church confesses in Acts and 1 Peter, is held open at full strength and never as a strawman, before the section ends with the free invitation to everyone who thirsts to come to the waters.
The New Heavens and the New Earth
The closing chapters widen the doors of the restored community: foreigners and eunuchs are gathered in, and the LORD's house is called a house of prayer for all peoples. Against worship that fasts while crushing the poor, chapter 58 names the fast God chooses, to loose the bonds of wickedness and share bread with the hungry; then the glory of the LORD rises on Zion and an anointed herald proclaims good news to the humble. The book ends where it has been moving all along, in new heavens and a new earth where the wolf and the lamb feed together and sorrow is no more.
Isaiah in the New Testament, and the Synthesis
No book outside the Psalms is quoted in the New Testament as often as Isaiah, and this closing module traces why the early church called it the fifth Gospel: Immanuel in Matthew, the voice in the wilderness in the Gospels, the suffering Servant in Acts and 1 Peter, the herald of chapter 61 on the lips of Jesus in Luke, the new creation in Revelation. That fuller reading is held in register, honoring Isaiah's plain sense and resisting any supersessionism. The capstone then gathers the whole course by reading the Holy Way of chapter 35, the ransomed of the LORD returning to Zion with singing, where holiness both judges and redeems in a single passage.
