“Then I saw an angel coming down from heaven, having the key to the bottomless pit and a great chain in his hand. He laid hold of the dragon, that serpent of old, who is the Devil and Satan, and bound him for a thousand years; and he cast him into the bottomless pit, and shut him up, and set a seal on him, so that he should deceive the nations no more till the thousand years were finished. But after these things he must be released for a little while. And I saw thrones, and they sat on them, and judgment was committed to them. And I saw the souls of those who had been beheaded for their witness to Jesus and for the word of God, who had not worshiped the beast or his image, and had not received his mark on their foreheads or on their hands. And they lived and reigned with Christ for a thousand years. But the rest of the dead did not live again until the thousand years were finished. This is the first resurrection. Blessed and holy is he who has part in the first resurrection. Over such the second death has no power, but they shall be priests of God and of Christ, and shall reign with Him a thousand years. Now when the thousand years have expired, Satan will be released from his prison and will go out to deceive the nations which are in the four corners of the earth, Gog and Magog, to gather them together to battle, whose number is as the sand of the sea. They went up on the breadth of the earth and surrounded the camp of the saints and the beloved city. And fire came down from God out of Heaven and devoured them.” Revelation 20:1-9.
“After these things I saw another angel coming down from heaven, having great authority, and the earth was illuminated with his glory. And he cried mightily with a loud voice, saying, ‘Babylon the great is fallen, is fallen, and has become a habitation of demons, a prison for every foul spirit, and a cage for every unclean and hated bird!’” Revelation 18:1-2.
“And war broke out in heaven: Michael and his angels fought against the dragon; and the dragon and his angels fought, but they did not prevail, nor was a place found for them in heaven any longer.” Revelation 12:7-8.
