I've been trying to read Revelation with Psalm 2 glasses on
3. Themes and Allusions
These vary in how specifically they echo Psalm 2 (i.e. I’m pretty convinced they do so intentionally, but judge for yourself).
The world united in revolt (Psalm 2:1-3): See 11:10, 13:3 and 7-14, 16:14, 17:13-14, 19:19. Two things strike me as interesting here in the way John draws on Psalm 2; first is the role which the beast and the dragon play in unifying the world and second is the way that the revolt against Christ is manifested in persecution/war against his people/saints/prophets.
God’s terrifying wrath (Psalm 2:5): See 6:15-17, 11:13. We should note that in Psalm 2 God’s wrath is manifested in his declaration that he’s established his King on Zion (Psalm 2:6), see 11:15-18 (a passage saturated in Psalm 2 allusions) and 14:1.
The swiftness of Judgment (Psalm 2:12): Psalm 2 warns that the Son’s ‘wrath is quickly kindled’ and Revelation 18 echoes this idea of swift and unexpected judgment, see 18:7, 8, 9, 10, 17, 19. The target is Babylon, which is associated with (but not the same as) the kings of the earth in 17:2 and 18:9.
The ‘Gospel Call’ (Psalm 2:10-12): This is echoed in the eternal gospel of 14:7 and the global reign of the Lord God Almighty in 15:3-4.
The Beattitude (Psalm 2:12): The ‘blessed are’ formula crops up all over Revelation (yes there are seven, none of them directly quote from Psalm 2, several of them come after ‘Psalm-2-esque’ proclamations of judgment and or warning), see 1:3, 14:13, 16:15, 19:9, 20:6, 22:7, 22:14. The ‘refuge’ is perhaps alluded to in 7:15.
