And
there came one of the seven angels which had the seven vials, and
talked with me, saying unto me, Come hither; I will shew unto thee the
judgment of the great whore that sitteth upon many waters:
With whom the kings of the earth have committed fornication, and the
inhabitants of the earth have been made drunk with the wine of her
fornication.So he carried me away in the spirit into the wilderness:
and I saw a woman sit upon a scarlet coloured beast, full of names of
blasphemy, having seven heads and ten horns. And the woman was arrayed
in purple and scarlet colour, and decked with gold and precious stones
and pearls, having a golden cup in her hand full of abominations and
filthiness of her fornication: And upon her forehead was a name
written, 'Mystery, Babylon the great, the mother of harlots and
abominations of the earth.' 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 great admiration. 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.'
And here is the mind which hath wisdom. The seven heads are seven
mountains, on which the woman sitteth.
