'Thousand Years' in the Bible

He gripped the dragon, that old serpent, who is the devil and Satan, and bound him for a thousand years,

and flung him into the bottomless pit, and shut and sealed it over him, so that he should seduce the nations no more, until the thousand years were completed. After that it is necessary to loose him for a little while.

And I saw thrones, and those who sat on them, and they were permitted to judge; and I saw the souls of those who had been beheaded for the testimony of Jesus, and for the Word of God, those who did not worship the beast nor his image, and who did not receive his brand upon their brow, or hands. And they lived and reigned with Christ for a thousand years.

The rest of the dead did not live until the thousand years were completed. This is the first resurrection.

Blessed and holy is he who has a part in the first resurrection; on such the second death has no power, but they will be God's priests, and Christ's; and will reign with him for a thousand years.

And when the thousand years have been completed, Satan will be loosed out of his prison,
