Revelation 20:3-5

New Century Version

³ Then he threw him into the bottomless pit, closed it, and locked it over him. The angel did this so he could not trick the people of the earth anymore until the thousand years were ended. After a thousand years he must be set free for a short time.

⁴ Then I saw some thrones and people sitting on them who had been given the power to judge. And I saw the souls of those who had been killed because they were faithful to the message of Jesus and the message from God. They had not worshiped the beast or his idol, and they had not received the mark of the beast on their foreheads or on their hands. They came back to life and ruled with Christ for a thousand years. ⁵ (The others that were dead did not live again until the thousand years were ended.) This is the first raising of the dead.
