Revelation 20:7-10

When the thousand years are over, Satan will be set free from his prison. Then he will go out to trick the nations in all the earth—Gog and Magog—to gather them for battle. There are so many people they will be like sand on the seashore. And Satan’s army marched across the earth and gathered around the camp of God’s people and the city God loves. But fire came down from heaven and burned them up. And Satan, who tricked them, was thrown into the lake of burning sulfur with the beast and the false prophet. There they will be punished day and night forever and ever.
