Revelation 20:7-10

Young's Literal Translation

⁷ And when the thousand years may be finished, the Adversary shall be loosed out of his prison,

⁸ and he shall go forth to lead the nations astray, that are in the four corners of the earth -- Gog and Magog -- to gather them together to war, of whom the number [is] as the sand of the sea;

⁹ and they did go up over the breadth of the land, and did surround the camp of the saints, and the beloved city, and there came down fire from God out of the heaven, and devoured them;

¹⁰ and the Devil, who is leading them astray, was cast into the lake of fire and brimstone, where [are] the beast and the false prophet, and they shall be tormented day and night -- to the ages of the ages.
