Revelation 12:3
King James Version
“And there appeared another wonder in heaven; and behold a great red dragon, having seven heads and ten horns, and seven crowns upon his heads.”
Context
1And there appeared a great wonder in heaven; a woman clothed with the sun, and the moon under her feet, and upon her head a crown of twelve stars:
2And she being with child cried, travailing in birth, and pained to be delivered.
3And there appeared another wonder in heaven; and behold a great red dragon, having seven heads and ten horns, and seven crowns upon his heads.
4And his tail drew the third part of the stars of heaven, and did cast them to the earth: and the dragon stood before the woman which was ready to be delivered, for to devour her child as soon as it was born.
5And she brought forth a man child, who was to rule all nations with a rod of iron: and her child was caught up unto God, and his throne.
6And the woman fled into the wilderness, where she hath a place prepared of God, that they should feed her there a thousand two hundred threescore days.
