Revelation 17:1-6 (ESV)

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 prostitute who is seated on many waters, ² with whom the kings of the earth have committed sexual immorality, and with the wine of whose sexual immorality the dwellers on earth have become drunk.” ³ And 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. ⁴ The woman was arrayed 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 sexual immorality. ⁵ And on her forehead was written a name of mystery: “Babylon the great, mother of prostitutes and of earth's abominations.” ⁶ And I saw the woman, drunk with the blood of the saints, the blood of the martyrs of Jesus.

When I saw her, I marveled greatly.
