Revelation 12:3-4, 16-17

And 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. And 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.

And the earth helped the woman, and the earth opened her mouth and swallowed up the river which the dragon cast out of his mouth. And the dragon waxed wroth with the woman, and went away to make war with the rest of her seed, that keep the commandments of God, and hold the testimony of Jesus
