REVELAION
SEVEN HEADS, TEN HORNS, THE WOMAN
Revelation 17:7-9
7 And the angel said unto me, Wherefore didst thou marvel? I will tell thee the mystery of the woman, and of the beast that carrieth her, which hath the seven heads and ten horns.

8 The beast that thou sawest was, and is not; and shall ascend out of the bottomless pit, and go into perdition: and they that dwell on the earth shall wonder, whose names were not written in the book of life from the foundation of the world, when they behold the beast that was, and is not, and yet is.

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

Revelation 17:12-13
12 And the ten horns which thou sawest are ten kings, which have received no kingdom as yet; but receive power as kings one hour with the beast.

13 These have one mind, and shall give their power and strength unto the beast.

Revelation 17:15-16
15 And he saith unto me, The waters which thou sawest, where the whore sitteth, are peoples, and multitudes, and nations, and tongues.

16 And the ten horns which thou sawest upon the beast, these shall hate the whore, and shall make her desolate and naked, and shall eat her flesh, and burn her with fire.

Revelation 17:18
18 And the woman which thou sawest is that great city, which reigneth over the kings of the earth.
