Rev 12:1-4

And a great sign appeared in heaven: a woman having been clothed with the sun, with the moon under her feet, and on her head a crown of twelve stars. (Rev 12:1)

And being pregnant, she was crying out, being in labor and being in great pain to give birth. (Rev 12:2)

And another sign appeared in heaven: and behold, a great, fiery dragon having seven heads and ten horns, and seven crowns on his heads. (Rev 12:3)

And his tail dragged a third of the stars of heaven and cast them to the earth. And the dragon stood before the woman who was about to give birth, so that whenever she might give birth, he might devour her Child. (Rev 12:4)
