Revelation 17:6-8

17:6 I saw that the woman was drunk with the blood of the saints and the blood of those who testified to Jesus. I was greatly astounded when I saw her. 17:7 But the angel said to me, “Why are you astounded? I will interpret for you the mystery of the woman and of the beast with the seven heads and ten horns that carries her. 17:8 The beast you saw was, and is not, but is about to come up from the abyss and then go to destruction. The inhabitants of the earth – all those whose names have not been written in the book of life since the foundation of the world – will be astounded when they see that the beast was, and is not, but is to come.

Revelation 17:18

17:18 As for the woman you saw, she is the great city that has sovereignty over the kings of the earth.”
