Revelation 12:7-12

7And there was war in the heaven: Michael and his angels went to war with the dragon. And the dragon fought, and his angels;

8and he prevailed not, nor was their place found any more in the heaven.

9And the great dragon was cast out, the ancient serpent, he who is called Devil and Satan, he who deceives the whole habitable world, he was cast out into the earth, and his angels were cast out with him.

10And I heard a great voice in the heaven saying, Now is come the salvation and the power and the kingdom of our 1God, and the authority of his Christ; for the accuser of our brethren has been cast out, who accused them before our 2God day and night:

11and they have overcome him by reason of the blood of the Lamb, and by reason of the word of their testimony, and have not loved their life even unto death.

12Therefore be full of delight, ye heavens, and ye that dwell in them. Woe to the earth and to the sea, because the devil has come down to you, having great rage, knowing he has a short time.
