Revelation 20:4-9

4Then I saw thrones and seated on them were those who had been given authority to judge. I also saw the souls of those who had been beheaded because of the testimony about Jesus and because of the word of God. These had not worshiped the beast or his image and had refused to receive his mark on their forehead or hand. They came to life and reigned with Christ for a thousand years.

5(The rest of the dead did not come to life until the thousand years were finished.) This is the first resurrection.

6Blessed and holy is the one who takes part in the first resurrection. The second death has no power over them, but they will be priests of God and of Christ, and they will reign with him for a thousand years.

7Now when the thousand years are finished, Satan will be released from his prison

8and will go out to deceive the nations at the four corners of the earth, Gog and Magog, to bring them together for the battle. They are as numerous as the grains of sand in the sea.

9They went up on the broad plain of the earth and encircled the camp of the saints and the beloved city, but fire came down from heaven and devoured them completely.
