'Thousand Years' in the Bible

And he took hold of the dragon, that old snake, who is the devil or Satan, and chained him up for a thousand years.

He threw him into the pit, and closed it and sealed it over him, to keep him from deceiving the nations anymore until the thousand years were ended. After that time, he must be released for a short while.

Then I saw thrones, with individuals sitting on them who had been given [authority] to judge. And I [also] saw the souls of those who had been decapitated because they had testified about Jesus and [had proclaimed] the message of God. [They are] the ones who had refused to worship the beast or his statue, and had not received his mark on their foreheads or on their hands. And these ones lived again and ruled with Christ for a thousand years.

(The rest of those who had died did not come [back] to life until the thousand years had ended). This is the first resurrection [from the dead].

The person who shares in this first resurrection is blessed and holy [i.e., for being so dedicated to God]. The second death does not have power over these people, but they will be priests of God and of Christ, and will rule with Him for the thousand years.

And when the thousand years are over, Satan will be released from his prison,
