Revelation 17:2, 5, 13, 18

with whom the kings of the earth have committed fornication, and the inhabitants of the earth have been made drunk with the wine of her fornication.

and upon her forehead was a name written, MYSTERY, BABYLON THE GREAT, THE MOTHER OF HARLOTS AND ABOMINATIONS OF THE EARTH.

These have one mind, and shall give their power and strength unto the beast.

And the woman which thou sawest is that great city, which reigneth over the kings of the earth.
