Revelation 12:1-4

And then a great wonder appeared in heaven: A woman was clothed with the sun, and the moon was under her feet, and a crown of twelve stars was on her head. She was pregnant and cried out with pain, because she was about to give birth. 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.
