(Revelation 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.

(Revelation 12:7) And there was war in heaven: Michael and his angels fought against the dragon; and the dragon fought and his angels,

(Revelation 12:8) And prevailed not; neither was their place found any more in heaven.
