What This Chapter Is About
God rebukes Israel for stubbornness — He declared things long ago so they could not credit idols. He refines Israel in the furnace of affliction. For His own name's sake He delays anger. Cyrus is His instrument. 'Go out from Babylon!' The section closes: 'There is no peace for the wicked.'
What Makes This Chapter Remarkable
The chapter is God's most frustrated address to Israel in Second Isaiah. The command to leave Babylon (v. 20) is the climactic imperative of chapters 40-48. The closing refrain 'there is no peace for the wicked' (v. 22) divides Second Isaiah into three sections (48:22, 57:21, and implicitly 66:24).
Translation Friction
The phrase becharttikha velo bekhesef (v. 10) is textually difficult: 'I chose you' or 'I tested you'? We followed the Masoretic text. The kur oni ('furnace of affliction') describes exile as purposeful refining. The 'no peace' refrain is abrupt after the joy of v. 20 — the juxtaposition is intentional.
Connections
The 'go out from Babylon' (v. 20) echoes Genesis 12:1 and anticipates Revelation 18:4. The refining-furnace image connects to Deuteronomy 4:20 and 1 Kings 8:51. The 'no peace' refrain recurs at 57:21.
**Tradition comparisons:** The Dead Sea Scrolls (1QIsaiah-a) preserve this chapter with notable variants: Verse 6: a possible variant in the verb form 'you have heard.' Verse 10: the scroll reads 'I have tested you in the furnace of affliction' with a possible variant in the preposition. Verse 17: 'I am the LORD your God who teaches you to profit' — identical. Verse 20: 'Go out from Babylon!' — ident.... See the [DSS Isaiah comparison](/dss-isaiah/48).
