'Thousand Years' in the Bible

But, beloved, be not ye ignorant of this one thing, that one day is with the Lord as a thousand years, and a thousand years as one day.

And he laid hold on the dragon, the old serpent, who is the devil and Satan, and bound him a thousand years,

And cast him into the bottomless pit, and shut him up, and set a seal upon him, that he might deceive the nations no more, till the thousand years should be fulfilled. After this he must be loosed for a small time.

And I saw thrones, and they sat on them, and judgment was given to them; and I saw the souls of them who had been beheaded for the testimony of Jesus, and for the word of God, and those who had not worshiped the wild beast nor his image, neither had received the mark on their forehead or on their hand; and they lived and reigned with Christ a thousand years.

The rest of the dead lived not again till the thousand years were ended. This is the first resurrection.

Happy and holy is he that hath a part in the first resurrection: over these 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 fulfilled, Satan shall be loosed out of his prison,
