Revelation 19:20

19:20 Now the beast was seized, and along with him the false prophet who had performed the signs on his behalf – signs by which he deceived those who had received the mark of the beast and those who worshiped his image. Both of them were thrown alive into the lake of fire burning with sulfur.

Revelation 20:14-15

20:14 Then Death and Hades were thrown into the lake of fire. This is the second death – the lake of fire. 20:15 If anyone’s name was not found written in the book of life, that person was thrown into the lake of fire.
