Revelation 19:20-21

20Then the beast was captured, and along with him the false prophet who had performed the signs before him by which he deceived those who had received the mark of the beast, as well as those who had worshiped his image. These two were thrown alive into the lake of fire burning with brimstone.

21The rest were killed with the sword coming out of the mouth of the One riding on the horse. And all the birds gorged themselves with their flesh.
