Revelation 12:7-9 Common English Bible (CEB)
Michael and the dragon
7 Then there was war in heaven: Michael and his angels fought the dragon. The dragon and his angels fought back, 8 but they did not prevail, and there was no longer any place for them in heaven. 9 So the great dragon was thrown down. The old snake, who is called the devil and Satan, the deceiver of the whole world, was thrown down to the earth; and his angels were thrown down with him.
