Revelation 20:7-10 - Satan's Release And Defeat
7 And when the thousand years are completed, Satan will be released from his prison 8 and he will go out to deceive the nations [that are] at the four corners of the earth, Gog and Magog, to assemble them for battle, {whose number} [is] like the sand of the sea. 9 And they went up on the broad plain of the earth and surrounded the fortified camp of the saints and the beloved city, and fire came down from heaven and consumed them. 10 And the devil who deceived them was thrown into the lake of fire and sulphur, where the beast and the false prophet also [are], and they will be tormented day and night {forever and ever}.
