Rev 17:3-8

And he led me away in the Spirit, into a deserted place. And I saw a woman sitting on a scarlet beast full of blasphemous names, having seven heads and ten horns. (Rev 17:3)

And the woman was clothed in purple and scarlet, gilded with gold and precious stones and pearls, having in her hand a golden cup being filled with abominations and the filthiness of the fornication of the earth. (Rev 17:4)

And on her forehead a name was written, a mystery: BABYLON THE GREAT, THE MOTHER OF HARLOTS AND OF THE ABOMINATIONS OF THE EARTH. (Rev 17:5)

I saw the woman, drunk with the blood of the saints and with the blood of the martyrs of Jesus. And when I saw her, I marveled with great amazement. (Rev 17:6)

But the angel said to me, "Why did you marvel? I will tell you the mystery of the woman and of the beast carrying her, which has the seven heads and the ten horns. (Rev 17:7)

The beast which you saw was, and is not, and is about to ascend out of the bottomless pit and go to perdition. And those who dwell on the earth shall marvel, whose name is not written in the Book of Life from the foundation of the world, when they see the beast that was, and is not, and shall be present. (Rev 17:8)
