Revelation 12:3-8

Then another wonder appeared in heaven: There was a giant red dragon with seven heads and seven crowns on each head. He also had ten horns. His tail swept a third of the stars out of the sky and threw them down to the earth. He stood in front of the woman who was ready to give birth so he could eat her baby as soon as it was born. Then the woman gave birth to a son who will rule all the nations with an iron rod. And her child was taken up to God and to his throne. The woman ran away into the desert to a place God prepared for her where she would be taken care of for one thousand two hundred sixty days. Then there was a war in heaven. Michael and his angels fought against the dragon, and the dragon and his angels fought back. But the dragon was not strong enough, and he and his angels lost their place in heaven.
