Then one of the seven angels who had the seven bowls came and said to me, "Come, I will show you the judgment of the great harlot who is seated upon many waters, with whom the kings of the earth have committed fornication, and with the wine of whose fornication the dwellers on earth have become drunk." And he carried me away in the Spirit into a wilderness, and I saw a woman sitting on a scarlet beast which was full of blasphemous names, and it had seven heads and ten horns. The woman was arrayed in purple and scarlet, and bedecked with gold and jewels and pearls, holding in her hand a golden cup full of abominations and the impurities of her fornication; and on her forehead was written a name of mystery: "BABYLON THE GREAT, MOTHER OF HARLOTS AND OF EARTH'S ABOMINATIONS." And I saw the woman, drunk with the blood of the saints and the blood of the martyrs of Jesus.
When I saw her I marveled greatly.
