Revelation 17:5-9

5The name written on her forehead was a mystery: babylon the great the mother of prostitutes and of the abominations of the earth.

6I saw that the woman was drunk with the blood of God’s holy people, the blood of those who bore testimony to Jesus. When I saw her, I was greatly astonished.

7Then the angel said to me: “Why are you astonished? I will explain to you the mystery of the woman and of the beast she rides, which has the seven heads and ten horns.

8The beast, which you saw, once was, now is not, and yet will come up out of the Abyss and go to its destruction. The inhabitants of the earth whose names have not been written in the book of life from the creation of the world will be astonished when they see the beast, because it once was, now is not, and yet will come.

9“This calls for a mind with wisdom. The seven heads are seven hills on which the woman sits.
