Revelation 17:3-12

And the angel carried me away in the Spirit into a wilderness; and I saw a woman sitting on a scarlet beast that was entirely covered with blasphemous names, having seven heads and ten horns. [Acts 10:10, 11] The woman was dressed in purple and scarlet, and adorned with gold, precious stones and pearls, [and she was] holding in her hand a gold cup full of the abominations and the filth of her [sexual] immorality. [Jer 51:7] And on her forehead a name was written, a mystery: “BABYLON THE GREAT, THE MOTHER OF PROSTITUTES (false religions, heresies) AND OF THE ABOMINATIONS OF THE EARTH.” I saw that the woman was drunk with the blood of the saints (God’s people), and with the blood of the witnesses of Jesus [who were martyred]. When I saw her, I wondered in amazement. But the angel said to me, “Why do you wonder? I will explain to you the mystery of the woman and of the beast that carries her, which has the seven heads and ten horns. “The beast that you saw was [once], but [now] is not, and he is about to come up out of the abyss (the bottomless pit, the dwelling place of demons) and go to destruction (perdition). And the inhabitants of the earth, whose names have not been written in the Book of Life from the foundation of the world, will be astonished when they see the beast, because he was and is not and is yet to come [to earth]. [Dan 7:3] Here is the mind which has wisdom [and this is what it knows about the vision]. The seven heads are seven hills on which the woman sits; and they are seven kings: five of whom have fallen, one exists and is reigning; the other [the seventh] has not yet come, and when he does come, he must remain a little while. And the beast that [once] was but is not, is himself also an eighth king and is one of the seven, and he goes to destruction (perdition). The ten horns that you saw are ten kings who have not yet received a kingdom, but [together] they receive authority as kings for a single hour [for a common purpose] along with the beast. [Dan 7:20-24]
