Revelation 20:7
King James Version
And when the thousand years are expired, Satan shall be loosed out of his prison,
Revelation 20:7 in context
But the rest of the dead lived not again until the thousand years were finished. This is the first resurrection.
Blessed and holy is he that hath part in the first resurrection: on such the second death hath no power, but they shall be priests of God and of Christ, and shall reign with him a thousand years.
And when the thousand years are expired, Satan shall be loosed out of his prison,
And shall go out to deceive the nations which are in the four quarters of the earth, Gog, and Magog, to gather them together to battle: the number of whom is as the sand of the sea.
And they went up on the breadth of the earth, and compassed the camp of the saints about, and the beloved city: and fire came down from God out of heaven, and devoured them.
