Revelation 19:20

Revelation 19:20 In-Context

18 in order that you may eat the flesh of kings, and the flesh of military tribunes, and the flesh of the powerful, and the flesh of horses and those seated on them, and the flesh of all [people], both free and slave, and small and great!"
19 And I saw the beast and the kings of the earth and their armies assembled to make war with the one who is seated on the horse and with his army.
20 And the beast was seized, and with him the false prophet who performed the signs before him, by which he deceived those who received the mark of the beast and those who had worshiped his image. The two were thrown alive into the lake of fire that burns with sulphur.
21 And the rest were killed by the sword of the one who is seated on the horse--the [sword] that comes out of his mouth--and all the birds gorged themselves on their flesh.
