What This Chapter Is About
Isaiah 27 concludes the four-chapter 'Isaiah's Apocalypse' with three decisive acts: the slaying of Leviathan, the tender renewal of God's vineyard, and the gathering of scattered exiles. On that day the LORD draws His great sword against Leviathan — the twisting serpent, the dragon of the sea — and slays it. Then comes a vineyard song (vv. 2-6) that deliberately reverses chapter 5's vineyard of disappointment: where the earlier vineyard produced wild grapes and was abandoned, this vineyard is guarded day and night by a God who has no wrath, who waters it every moment. Israel will bud, blossom, and fill the world with fruit. The middle section addresses Israel's discipline: Jacob's guilt is atoned when altar stones are crushed to chalk and Asherah poles fall. The chapter — and the entire Apocalypse — closes with the sound of the great trumpet (shofar gadol), summoning the lost and scattered from Assyria and Egypt to worship the LORD on the holy mountain in Jerusalem. We rendered this concluding chapter with attention to its tone of resolution and restoration, preserving the vineyard reversal and the triumphant finality of the great trumpet.
What Makes This Chapter Remarkable
The vineyard song (vv. 2-6) is a deliberate revision of Isaiah 5:1-7. In chapter 5, the vineyard was lovingly planted but produced bad fruit, and God tore down its walls in judgment. Here, the same God tends a vineyard with no anger — He waters it constantly, guards it day and night, and invites even thorns and briers to make peace with Him rather than face burning. The shift from wrath to tenderness is theologically momentous: God has moved from judgment to restoration. The Leviathan slaying (v. 1) draws on ancient Near Eastern combat mythology (the Ugaritic texts describe Baal's battle with the sea-serpent Litanu/Lotan) but radicalizes it: YHWH defeats cosmic chaos not in primordial time but on the eschatological 'that day.' The great trumpet (v. 13) becomes a key image in later Jewish and Christian eschatology (cf. Matt 24:31; 1 Cor 15:52; 1 Thess 4:16).
Translation Friction
The Leviathan references (v. 1) name three entities — or possibly one entity with three descriptions: 'Leviathan the fleeing serpent, Leviathan the twisting serpent, and the dragon in the sea.' The relationship between these figures (one monster, two, or three?) is debated. The Ugaritic parallel (KTU 1.5.I.1-3) lists similar epithets for a single creature, suggesting Isaiah describes one cosmic enemy with multiple aspects. The 'altar stones crushed to chalk' (v. 9) as the condition for atonement is surprising — it appears to require the destruction of pagan altars (or possibly even Israelite altars that had been corrupted) as the price of forgiveness. We rendered bezot ('by this') without specifying what is being atoned for, as the Hebrew leaves the referent somewhat open. The 'city' in verses 10-11 (fortified, forsaken, a pasture for calves) may be Jerusalem under judgment, the same unnamed city of chaos, or a composite image.
Connections
Leviathan (v. 1) appears in Job 41, Psalm 74:14, and Psalm 104:26, and connects to Revelation 12-13 (the dragon and sea-beast). The vineyard song (vv. 2-6) reverses Isaiah 5:1-7 and anticipates Jesus' vineyard parables (Matt 21:33-46; John 15:1-8). The great trumpet (v. 13) connects to Leviticus 25:9 (Jubilee trumpet), Matthew 24:31 ('He will send His angels with a great trumpet'), 1 Corinthians 15:52 ('at the last trumpet'), and 1 Thessalonians 4:16. The gathering of exiles from Assyria and Egypt fulfills the promise of Isaiah 11:11-12. Worship on the holy mountain (v. 13) concludes the Apocalypse with the same image that opened it: the LORD reigning on Mount Zion (24:23).
**Tradition comparisons:** The Dead Sea Scrolls (1QIsaiah-a) preserve this chapter with notable variants: Verse 1 (Leviathan slain) has a minor variant. Verse 9 has a variant in the description of altar stones. The cosmic drama and vineyard reversal (contrast ch. 5) are preserved identically in both traditions..
