Revelation 17:3-12 CSB
Then he carried me away in the Spirit to a wilderness.
I saw a woman sitting on a scarlet beast that was covered with blasphemous names and had seven heads and ten horns. The woman was dressed in purple and scarlet, adorned with gold, jewels, and pearls. She had a golden cup in her hand filled with everything detestable and with the impurities of her prostitution. On her forehead was written a name, a mystery: BABYLON THE GREAT, THE MOTHER OF PROSTITUTES AND OF THE DETESTABLE THINGS OF THE EARTH. Then I saw that the woman was drunk with the blood of the saints and with the blood of the witnesses to Jesus. When I saw her, I was greatly astonished.
Then the angel said to me, “Why are you astonished? I will explain to you the mystery of the woman and of the beast, with the seven heads and the ten horns, that carries her. The beast that you saw was, and is not, and is about to come up from the abyss and go to destruction. Those who live on 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 that was, and is not, and is to come. This calls for a mind that has wisdom.
“The seven heads are seven mountains on which the woman is seated. They are also seven kings: Five have fallen, one is, the other has not yet come, and when he comes, he must remain for only a little while. The beast that was and is not, is itself an eighth king, but it belongs to the seven and is going to destruction. The ten horns you saw are ten kings who have not yet received a kingdom, but they will receive authority as kings with the beast for one hour.
