Revelation 12:7-9

12:7 And there was war in heaven: Michael and his angels fought against the dragon; and the dragon fought and his angels, 12:8 And prevailed not; neither was their place found any more in heaven. 12:9 And the great dragon was cast out, that old serpent, called the Devil, and Satan, which deceiveth the whole world: he was cast out into the earth, and his angels were cast out with him.
