Revelation 12:3-4

Darby Translation

³ And another sign was seen in the heaven: and behold, a great red dragon, having seven heads and ten horns, and on his heads seven diadems;

⁴ and his tail draws the third part of the stars of the heaven; and he cast them to the earth. And the dragon stood before the woman who was about to bring forth, in order that when she brought forth he might devour her child.
