Revelation 20:7-10

After the thousand years are over, Satan will be let loose from his prison and will go out and deceive the nations of the four corners of the earth, Gog and Magog. He will bring them together for battle, and they will be as numerous as grains of sand on the seashore. They spread out over the earth and surrounded the camp of God’s holy believers and the beloved city. But fire came down from heaven and completely destroyed them. Then the devil who had deceived them was thrown into the same place with the wild beast and the false prophet—the lake of fire and sulfur—where they will be tormented day and night forever and ever.
