Revelation 20:7-9

7When the thousand years has ended, satan shall be released from his prison,

8and he shall come out to deceive the nations at the four corners of the earth, Gog and Magog, to gather them for the battle. Their number is like the sand of the sea.

9And they came up on the broad plain of the earth and surrounded the camp of the kedoshim and the beloved city—but fire fell from heaven and consumed them.
