Revelation 12:1-4

1And a great sign was seen in heaven: a woman arrayed with the sun, and the moon under her feet, and upon her head a crown of twelve stars;

2and she was with child; and she crieth out, travailing in birth, and in pain to be delivered.

3And there was seen another sign in heaven: and behold, a great red dragon, having seven heads and ten horns, and upon his heads seven diadems.

4And his tail draweth the third part of the stars of heaven, and did cast them to the earth: and the dragon standeth before the woman that is about to be delivered, that when she is delivered he may devour her child.
