Revelation 12:6-8

Amplified Bible, Classic Edition

⁶ And the woman [herself] fled into the desert (wilderness), where she has a retreat prepared [for her] by God, in which she is to be fed and kept safe for 1,260 days (42 months; three and one-half years).

⁷ Then war broke out in heaven; Michael and his angels went forth to battle with the dragon, and the dragon and his angels fought.

⁸ But they were defeated, and there was no room found for them in heaven any longer.
