Revelation 12:7-9

21st Century King James Version

⁷ And there was war in Heaven: Michael and his angels fought against the dragon; and the dragon fought and his angels,

⁸ and prevailed not; neither was their place found any more in Heaven.

⁹ And the great dragon was cast out — that serpent of old called the Devil and Satan, who deceiveth the whole world. He was cast out onto the earth, and his angels were cast out with him.
