Revelation 12:7-9

Young's Literal Translation

⁷ And there came war in the heaven; Michael and his messengers did war against the dragon, and the dragon did war, and his messengers,

⁸ and they did not prevail, nor was their place found any more in the heaven;

⁹ and the great dragon was cast forth -- the old serpent, who is called `Devil,' and `the Adversary,' who is leading astray the whole world -- he was cast forth to the earth, and his messengers were cast forth with him.
