Revelation 20:7-9

The Judgment of Satan 7When the thousand years are over, Satan will be released from his prison 8and will go out to deceive the nations in the four corners of the earth—Gog and Magog—and to gather them for battle. In number they are like the sand on the seashore. 9They marched across the breadth of the earth and surrounded the camp of God’s people, the city he loves. But fire came down from heaven and devoured them.
