Revelation 20:7-9

King James Version

⁷ And when the thousand years are expired, Satan shall be loosed out of his prison,

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.

⁹ And they went up on the breadth of the earth, and compassed the camp of the saints about, and the beloved city: and fire came down from God out of heaven, and devoured them.
