The Holy Bible
Revelation 12 : 7 - 9
7 | And war broke out in heaven: Michael and his angels fought with the dragon; and the dragon and his angels fought, |
8 | but they did not prevail, nor was a place found for them in heaven any longer. |
9 | So 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. |
