Revelation 20:14-15; Revelation 20:8

14 And death and hell were cast into the lake of fire. This is the second death.

15 And whosoever was not found written in the book of life was cast into the lake of fire.

8 And shall go out to deceive the nations which are in the four quarters of the earth, Gog and Magog, to gather them together to battle: the number of whom is as the sand of the sea.
