And when the thousand years are ended, Satan shall be loosed out of his prison, 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. And they went up over the breadth of the earth, and encircled the camp of the saints, and the beloved city: and fire came down from God out of heaven, and devoured them.

And the devil that deceived them was cast into the lake of fire and brimstone, where the beast and the false prophet are, and shall be tormented day and night forever and ever.
(Revelation 20:7-10)
