Revelation 20:7-9

7When the thousand years are complete, 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—to assemble them for battle. Their number is like the sand of the seashore.

9And they marched across the broad expanse of the earth and surrounded the camp of the saints and the beloved city. But fire came down from heaven1 and consumed them.
