Revelation 19:20 in the King James Version
And the beast was taken, and with him the false prophet that wrought miracles before him, with which he deceived them that had received the mark of the beast, and them that worshipped his image. These both were cast alive into a lake of fire burning with brimstone.
Context
19 I saw the beast, the kings of the earth, and their armies, gathered together to make war against him who sat on the horse and against his army.
20 The beast was taken, and with him the false prophet who worked the signs in his sight, with which he deceived those who had received the mark of the beast and those who worshiped his image. These two were thrown alive into the lake of fire that burns with sulfur.
21 The rest were killed with the sword of him who sat on the horse, the sword which came out of his mouth. So all the birds were filled with their flesh.
