Revelation 17:4-6

4And the woman was clothed in purple and scarlet, and had ornaments of gold and precious stones and pearls, having a golden cup in her hand full of abominations and the unclean things of her fornication;

5and upon her forehead a name written, Mystery, great Babylon, the mother of the harlots, and of the abominations of the earth.

6And I saw the woman drunk with the blood of the saints, and with the blood of the witnesses of Jesus. And I wondered, seeing her, with great wonder.
