What This Chapter Is About
Isaiah 66 is the final chapter of the book and brings its grand themes to their ultimate resolution. God declares that heaven is His throne and earth His footstool — no temple can contain Him, yet He looks with favor on the humble and contrite spirit. The chapter denounces those who trust in empty ritual while practicing abomination, then pivots to one of the most remarkable images in all prophecy: Zion gives birth to a nation in a single day. God comforts His people as a mother comforts her child. The nations stream to Jerusalem to see God's glory, and priests are taken from among the Gentiles. The book closes with a vision of universal worship — all flesh coming before the LORD — alongside a final, unflinching image of judgment: the worm that does not die and the fire that is not quenched.
What Makes This Chapter Remarkable
Verse 1 ('Heaven is My throne, earth is My footstool') is quoted by Stephen in his defense before the Sanhedrin (Acts 7:49) to argue that God cannot be confined to a building. Verse 13 ('As a mother comforts her child, so I will comfort you') is one of the rare instances where God is explicitly compared to a mother. The final verse (v.24) provides the imagery Jesus uses for Gehenna in Mark 9:48 ('where the worm does not die and the fire is not quenched'), making it one of the most consequential verses in eschatological theology.
Translation Friction
The juxtaposition of universal worship (v.23) and unending judgment (v.24) in consecutive verses creates deliberate theological friction. We have not softened either pole. The maternal imagery for God (v.13) is preserved without qualification — Isaiah uses the verb nacham ('comfort') with an explicitly feminine comparison (ke'ish asher immo tenachamenu). The identity of the 'brethren' brought as an offering from the nations (v.20) is left open, as the Hebrew permits both Israelite returnees and Gentile converts.
Connections
Verse 1 is quoted in Acts 7:49 (Stephen's speech). Verse 7 ('before she was in labor she gave birth') anticipates the sudden, miraculous birth of the church at Pentecost. Verse 13's maternal comfort echoes Isaiah 49:15 ('Can a mother forget her nursing child?'). The final verse (v.24) provides the source text for Jesus' Gehenna teaching in Mark 9:43-48. The gathering of all nations (v.18) anticipates the Great Commission (Matthew 28:19) and the multitude from every nation in Revelation 7:9.
**Tradition comparisons:** The Dead Sea Scrolls (1QIsaiah-a) preserve this chapter with notable variants: Verse 1 — 'Heaven is My throne' (quoted in Acts 7:49) — is stable. Verse 7 has a moderate variant in the birth-before-labor imagery. Verse 17 has a notable reading in the description of pagan purification rites. Verse 20 contains a moderate variant regarding the offerings brought from all nations.... See the [DSS Isaiah comparison](/dss-isaiah/66). Targum Jonathan provides interpretive renderings: The throne is 'of my glory' (diyeqari), and the footstool is 'of my Shekinah.' Both heaven and earth are described in terms of glory and Shekinah, creating a comprehensive two-world Shekinah cosmology... See [Targum Jonathan on Isaiah](/targum/isaiah).
