Revelation 17:4-6

New Revised Standard Version, Anglicised Catholic Edition

⁴ 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; ⁵ and on her forehead was written a name, a mystery: ‘Babylon the great, mother of whores and of earth’s abominations.’ ⁶ 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.
