Revelation 17:6-7

UKJV(i) 6 And I saw the woman drunken with the blood of the saints, and with the blood of the martyrs of Jesus: and when I saw her, I wondered with great admiration. 7 And the angel said unto me, Wherefore did you marvel? I will tell you the mystery of the woman, and of the beast that carries her, which has the seven heads and ten horns.
