Revelation 12:7-13

And there was war in heaven: Michael and his angels going forth to war with the dragon; and the dragon warred and his angels; and they prevailed not, neither was their place found any more in heaven. And the great dragon was cast down, the old serpent, he that is called the Devil and Satan, the deceiver of the whole world; he was cast down to the earth, and his angels were cast down with him. And I heard a great voice in heaven, saying, Now is come the salvation, and the power, and the kingdom of our God, and the authority of his Christ: for the accuser of our brethren is cast down, who accuseth them before our God day and night. And they overcame him because of the blood of the Lamb, and because of the word of their testimony; and they loved not their life even unto death. Therefore rejoice, O heavens, and ye that dwell in them. Woe for the earth and for the sea: because the devil is gone down unto you, having great wrath, knowing that he hath but a short time. And when the dragon saw that he was cast down to the earth, he persecuted the woman that brought forth the man child.
