Revelation 17:5-7

21st Century King James Version

⁵ and upon her forehead was a name written: Mystery, Babylon the Great, Mother of Harlots and Abominations of the Earth.

⁶ And I saw that the woman was drunk with the blood of the saints and with the blood of the martyrs of Jesus. And when I saw her, I wondered with great amazement.

⁷ And the angel said unto me, “Why dost thou marvel? I will tell thee the mystery of the woman and of the beast that carrieth her, which hath the seven heads and ten horns.
