Revelation 12:7-9 ▼

7 Then war broke out in heaven: Michael and his angels fought against the dragon. The dragon and his angels also fought,

8 but he could not prevail, and there was no place for them in heaven any longer.

9 So the great dragon was thrown out—the ancient serpent, who is called the devil and Satan, the one who deceives the whole world. He was thrown to earth, and his angels with him.
