Revelation 12:7-8

War in Heaven

12:7 Then war broke out in heaven: Michael and his angels fought against the dragon, and the dragon and his angels fought back. 12:8 But the dragon was not strong enough to prevail, so there was no longer any place left in heaven for him and his angels.

Revelation 12:17

12:17 So the dragon became enraged at the woman and went away to make war on the rest of her children, those who keep God’s commandments and hold to the testimony about Jesus. (12:18) And the dragon stood on the sand of the seashore.
