Revelation 12:7
King James Version
“And there was war in heaven: Michael and his angels fought against the dragon; and the dragon fought and his angels,”
Context
4And his tail drew the third part of the stars of heaven, and did cast them to the earth: and the dragon stood before the woman which was ready to be delivered, for to devour her child as soon as it was born.
5And she brought forth a man child, who was to rule all nations with a rod of iron: and her child was caught up unto God, and his throne.
6And the woman fled into the wilderness, where she hath a place prepared of God, that they should feed her there a thousand two hundred threescore days.
7And there was war in heaven: Michael and his angels fought against the dragon; and the dragon fought and his angels,
8And prevailed not; neither was their place found any more in heaven.
9And the great dragon was cast out, that old serpent, called the Devil, and Satan, which deceiveth the whole world: he was cast out into the earth, and his angels were cast out with him.
10And I heard a loud voice saying in heaven, Now is come salvation, and strength, and the kingdom of our God, and the power of his Christ: for the accuser of our brethren is cast down, which accused them before our God day and night.
