Revelation 17:7-9

New Matthew Bible

⁷ And the angel said to me, Why do you marvel? I will show you the mystery of the woman, and of the beast that bears her, which has seven heads and ten horns. ⁸ The beast that you see was, and is not, and will ascend out of the bottomless pit, and will go into perdition. And they who dwell on the earth (whose names are not written in the book of life from the beginning of the world) will marvel when they see the beast that was, and is not, and yet is.

⁹ And here is a mind that has wisdom: The seven heads are seven mountains on which the woman sits.
