Revelation 20:6-8

Darby Translation

⁶ Blessed and holy he who has part in the first resurrection: over these the second death has no power; but they shall be priests of God and of the Christ, and shall reign with him a thousand years.

⁷ And when the thousand years have been completed, Satan shall be loosed from his prison,

⁸ and shall go out to deceive the nations which [are] in the four corners of the earth, Gog and Magog, to gather them together to the war, whose number [is] as the sand of the sea.
