Revelation 20:6-8

American Standard Version

⁶ Blessed and holy is he that hath part in the first resurrection: over these the second death hath no ^[a]power; but they shall be priests of God and of Christ, and shall reign with him ^[b]a thousand years.

⁷ And when the thousand years are finished, Satan shall be loosed out of his prison, ⁸ and shall come forth to deceive the nations which are in the four corners of the earth, Gog and Magog, to gather them together to the war: the number of whom is as the sand of the sea.
