Revelation 12:3-4

3Then another wonderful thing appeared in the sky. It was a very big red dragon. It had seven heads and ten horns. There was a crown on each head.

4Its tail beat away a third of the stars from the sky. It threw them down on the earth. Then the dragon stood in front of the woman who would soon give birth to her baby. He was waiting there to eat her child as soon as he was born.
