Revelation 17:2, 5, 13, 18

with whom the kings of the earth committed acts of immorality, and those who dwell on the earth were made drunk with the wine of her immorality.”

and on her forehead a name was written, a mystery, “BABYLON THE GREAT, THE MOTHER OF HARLOTS AND OF THE ABOMINATIONS OF THE EARTH.”

These have one purpose, and they give their power and authority to the beast.

The woman whom you saw is the great city, which reigns over the kings of the earth.”
