Revelation 20:7-9
Satan’s Final Defeat
20:7 Now when the thousand years are finished, Satan will be released from his prison
20:8 and will go out to deceive the nations at the four corners of the earth, Gog and Magog, to bring them together for the battle. They are as numerous as the grains of sand in the sea.
20:9 They went up on the broad plain of the earth and encircled the camp of the saints and the beloved city, but fire came down from heaven and devoured them completely.
