Revelation 12:6-8

American Standard Version

⁶ And the woman fled into the wilderness, where she hath a place prepared of God, that there they may nourish her a thousand two hundred and threescore days.

⁷ And there was war in heaven: Michael and his angels going forth to war with the dragon; and the dragon warred and his angels; ⁸ and they prevailed not, neither was their place found any more in heaven.
