Isaiah

Introduction

Isaiah is the first and greatest of the Major Prophets, and the longest prophetic book in the Old Testament. The prophet Isaiah, son of Amoz (not to be confused with the prophet Amos), ministered in Jerusalem during the reigns of kings Uzziah, Jotham, Ahaz, and Hezekiah of Judah (Isaiah 1:1), spanning roughly from 740 to 700 BC. His call came "in the year that King Uzziah died" (Isaiah 6:1), and he served as a court prophet with direct access to the royal household. Isaiah was married to a woman he calls "the prophetess" (Isaiah 8:3), and he had at least two sons whose names were themselves prophetic signs: Shear-jashub ("a remnant shall return") and Maher-shalal-hash-baz ("swift is the plunder, speedy is the prey"). His audience was primarily the kingdom of Judah and the city of Jerusalem during a turbulent period that saw the fall of the northern kingdom of Israel to Assyria in 722 BC and the Assyrian siege of Jerusalem in 701 BC.

Isaiah is arguably the most theologically rich book in the Old Testament and is the most frequently quoted Old Testament book in the New Testament. Its sweeping vision encompasses God's judgment on sin, the promise of a faithful remnant, the coming of a messianic King and a suffering Servant, and the ultimate renewal of all creation. The book's distinctive title for God — "the Holy One of Israel" — appears over twenty-five times, binding together its themes of divine holiness, human sinfulness, and redemptive grace. The question of authorship has been a major focus of scholarly discussion. The traditional view, held throughout the church's history, attributes the entire book to Isaiah son of Amoz. Since the late eighteenth century, many scholars have proposed that chapters 40–55 (sometimes called "Deutero-Isaiah") and chapters 56–66 ("Trito-Isaiah") were composed by later prophetic figures writing during and after the Babylonian exile. Conservative Protestant scholars have offered substantial arguments for the unity of the book, pointing to its consistent theological vocabulary, its literary coherence, and the New Testament's attribution of passages from all sections to "Isaiah the prophet" (e.g., John 12:38-41, which quotes from both Isaiah 53:1 and Isaiah 6:10). Whether one holds to single or composite authorship, the canonical book of Isaiah stands as a unified theological masterpiece that the church receives as the word of God.

Structure

Isaiah can be divided into several major sections, with chapters 36–39 serving as a historical hinge between the book's two great halves:

Part 1: Judgment and Promise — The Book of the Lord's Indictment (Chapters 1–12)

• The LORD's Case against Judah (1:1–5:30) — Oracles of judgment and calls to repentance, including the song of the vineyard
• Isaiah's Commission (6:1–13) — The prophet's throne-room vision and call
• The Book of Immanuel (7:1–12:6) — Messianic prophecies set against the backdrop of the Syro-Ephraimite crisis, culminating in visions of a coming King and a song of thanksgiving

Part 2: Oracles against the Nations (Chapters 13–23)

• Prophetic burdens against Babylon, Assyria, Philistia, Moab, Damascus, Cush, Egypt, Edom, Arabia, Jerusalem, and Tyre — demonstrating the LORD's sovereignty over all nations

Part 3: The Isaiah Apocalypse (Chapters 24–27)

• A cosmic vision of universal judgment and ultimate salvation, including the LORD's feast on His holy mountain, the defeat of death, and a song of the redeemed

Part 4: Woe Oracles — Judgment on the Unfaithful (Chapters 28–35)

• A series of woes against Ephraim and Judah for trusting in alliances with Egypt rather than the LORD, concluding with a vision of the ransomed returning to Zion

Part 5: Historical Narrative (Chapters 36–39)

• The Assyrian crisis under Sennacherib and Hezekiah's faith (Isaiah 36:1–Isaiah 37:38), Hezekiah's illness and recovery (Isaiah 38:1-22), and the visit from Babylon that foreshadows the exile (Isaiah 39:1-8). These chapters parallel 2 Kings 18:13–2 Kings 20:19.

Part 6: The Book of Comfort (Chapters 40–55)

• The LORD as Incomparable Creator and Redeemer (40–48) — Comfort for the exiles, the folly of idolatry, and Cyrus as God's anointed instrument of deliverance
• The Servant of the LORD (49–55) — The Servant Songs reach their climax in the suffering and exaltation of the Servant (Isaiah 52:13–Isaiah 53:12), followed by invitations to participate in God's covenant of grace

Part 7: Future Glory — The Consummation of God's Purposes (Chapters 56–66)

• The extension of salvation to foreigners and eunuchs, rebukes of unfaithfulness, the Anointed Conqueror, prayers for deliverance, and the vision of new heavens and a new earth (Isaiah 65:17, Isaiah 66:22)

Key Themes

• The Holy One of Israel — Isaiah's characteristic name for God, emphasizing His transcendent holiness and His covenant relationship with His people
• Judgment and Salvation — The inseparable pairing of divine judgment on sin and divine deliverance for the faithful, often within the same oracle
• The Remnant — Though judgment will devastate the nation, a faithful remnant will survive and become the seed of a restored people (Isaiah 10:20-22)
• The Messianic King — Prophecies of a coming Davidic ruler who will reign in justice and peace (Isaiah 9:6-7, Isaiah 11:1-10)
• The Suffering Servant — Four "Servant Songs" (Isaiah 42:1-9, Isaiah 49:1-13, Isaiah 50:4-9, Isaiah 52:13–Isaiah 53:12) depicting a figure who bears the sins of the people — understood by the New Testament as fulfilled in Jesus Christ
• The New Creation — The vision of a renewed cosmos where righteousness dwells (Isaiah 65:17-25)
