Revelation 17:6-10

And I saw the woman drunk with the blood of the saints, and with the blood of the witnesses of Jesus. When I saw her, I wondered greatly.

And the angel said to me, “Why do you wonder? I will tell you the mystery of the woman and of the beast that carries her, which has the seven heads and the ten horns.

“The beast that you saw was, and is not, and is about to come up out of the abyss and go to destruction. And those who live on the earth, whose names have not been written in the book of life from the foundation of the world, will wonder when they see the beast, that he was, and is not, and will come.

Here is the mind which has wisdom. The seven heads are seven mountains upon which the woman sits,

and they are seven kings; five have fallen, one is, the other has not yet come; and when he comes, he must remain a little while.
