Revelation 17:7-11

7Then the angel said to me, “Why are you astonished? I will explain to you the mystery of the woman and of the beast, with the seven heads and the ten horns, that carries her.

8The beast that you saw was, and is not, and is about to come up from the abyss and go to destruction. Those who live on the earth whose names have not been written in the book of life from the foundation of the world will be astonished when they see the beast that was, and is not, and is to come.

9This calls for a mind that has wisdom. “The seven heads are seven mountains on which the woman is seated. They are also seven kings:

10Five have fallen, one is, the other has not yet come, and when he comes, he must remain for only a little while.

11The beast that was and is not, is itself an eighth king, but it belongs to the seven and is going to destruction.
