Revelation 19:20-21

20But the beast was captured along with the false prophet, who on its behalf had performed signs deceiving those who had the mark of the beast and worshiped its image. Both the beast and the false prophet were thrown alive into the fiery lake of burning sulfur. 21And the rest were killed with the sword that proceeded from the mouth of the One seated on the horse.

And all the birds gorged themselves on their flesh.
