Revelation 17:8

5 and upon her forehead a name written, MYSTERY, BABYLON THE GREAT, THE MOTHER OF THE HARLOTS AND OF THE ABOMINATIONS OF THE EARTH.

6 And I saw the woman drunken with the blood of the saints, and with the blood of the martyrs of Jesus. And when I saw her, I wondered with a great wonder.

7 And the angel said unto me, Wherefore didst thou wonder? I will tell thee the mystery of the woman, and of the beast that carrieth her, which hath the seven heads and the ten horns.

8 The beast that thou sawest was, and is not; and is about to come up out of the abyss, and to go into perdition. And they that dwell on the earth shall wonder, [they] whose name hath not been written in the book of life from the foundation of the world, when they behold the beast, how that he was, and is not, and shall come.

9 Here is the mind that hath wisdom. The seven heads are seven mountains, on which the woman sitteth:

10 and they are seven kings; the five are fallen, the one is, the other is not yet come; and when he cometh, he must continue a little while.

11 And the beast that was, and is not, is himself also an eighth, and is of the seven; and he goeth into perdition.
