Revelation 17:9-12

9And here is the mind which hath wisdom. The seven heads are seven mountains, on which the woman sitteth.

10And there are seven kings: five are fallen, and one is, and the other is not yet come; and when he cometh, he must continue a short space.

11And the beast that was, and is not, even he is the eighth, and is of the seven, and goeth into perdition.

12And the ten horns which thou sawest are ten kings, which have received no kingdom as yet; but receive authority as kings one hour with the beast.
