'Thousand Years' in the Bible

But, beloved, let not this one thing escape you, that one day with the Lord is as a thousand years, and a thousand years as one day.

And he seized the dragon, the old serpent, which is the Devil and Satan, and bound him for a thousand years,

and cast him into the abyss, and shut it, and sealed it over him, that he should deceive the nations no more, until the thousand years should be finished; after these things he must be loosed for a little time.

And I saw thrones, and they sat upon them; and judgment was given to them; and I saw the souls of those who had been beheaded because of the testimony of Jesus, and because of the word of God; and such as worshiped not the beast, neither his image, and received not the mark upon their forehead and upon their hand; and they lived, and reigned with Christ a thousand years.

The rest of the dead lived not until the thousand years should be finished. This is the first resurrection.

Happy and holy is he who has part in the first resurrection; over these the second death has no authority; but they shall be priests of God and of Christ, and shall reign with Him a thousand years.

And, when the thousand years are finished, Satan will be loosed out of his prison,
