She cried out in pain, laboring to give birth. ³Another sign was seen in heaven. Behold, a great red dragon, having seven heads and ten horns, and on his heads seven crowns. ⁴His tail drew one third of the stars of the sky, and threw them to the earth. The dragon stood before the woman who was about to give birth, so that when she gave birth he might devour her child.
