Revelation 19:20-21

But the beast was captured and with him the false prophet who did the miracles for the beast. The false prophet had used these miracles to trick those who had the mark of the beast and worshiped his idol. The false prophet and the beast were thrown alive into the lake of fire that burns with sulfur. And their armies were killed with the sword that came out of the mouth of the rider on the horse, and all the birds ate the bodies until they were full.
