Revelation 12:7-9

7And war broke out in heaven: Michael and his angels fought with the dragon; and the dragon and his angels fought,

8but they did not prevail, nor was a place found for them in heaven any longer.

9So the great dragon was cast out, that serpent of old, called the Devil and Satan, who deceives the whole world; he was cast to the earth, and his angels were cast out with him.
