Revelation 20:7

7 When the thousand years are up, Satan will be let loose from his cell,

Revelation 20:7 In-Context

5 The rest of the dead did not live until the thousand years were up. This is the first resurrection -
6 and those involved most blessed, most holy. No second death for them! They're priests of God and Christ; they'll reign with him a thousand years.
7 When the thousand years are up, Satan will be let loose from his cell,
8 and will launch again his old work of deceiving the nations, searching out victims in every nook and cranny of earth, even Gog and Magog! He'll talk them into going to war and will gather a huge army, millions strong.
9 They'll stream across the earth, surround and lay siege to the camp of God's holy people, the Beloved City. They'll no sooner get there than fire will pour out of Heaven and burn them up.
