Revelation 19: John continues telling the story of God's great, final battle now including Jesus's 2nd coming. Using the story and metaphors from Ezekeil 38-39 as prophetic fulfillment, he shows evil being lured in only for it to collapse upon itself and bring self-defeat and utter humiliation. It's another scene if non-violent divine judgement.
This episode explores Gog and Magog, the birds of the air consuming flesh, and John's own original judgement metaphor of the Lake of Fire.
