Revelation 19:20-21

20But the beast was captured, and with it the false prophet who had performed the signs on its behalf. With these signs he had deluded those who had received the mark of the beast and worshiped its image. The two of them were thrown alive into the fiery lake of burning sulfur.

21The rest were killed with the sword coming out of the mouth of the rider on the horse, and all the birds gorged themselves on their flesh.
