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 whore who is seated on many waters,
with whom the kings of the earth have committed fornication, and with the wine of whose fornication the inhabitants of the earth have become drunk."
So he carried me away in the spirit into a wilderness, and I saw a woman sitting on a scarlet beast that was full of blasphemous names, and it had seven heads and ten horns.
References for Revelation 17:3
The woman was clothed in purple and scarlet, and adorned 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, a mystery: "Babylon the great, mother of whores and of earth's abominations."
And I saw that the woman was drunk with the blood of the saints and the blood of the witnesses to Jesus. When I saw her, I was greatly amazed.
