'Babylon the Great' in the Bible

Then another angel, a second one, followed, saying, “Fallen, fallen is Babylon the great, she who has made all nations drink the wine of the passion of her immorality [corrupting them with idolatry].”

And on her forehead a name was written, a mystery: “BABYLON THE GREAT, THE MOTHER OF PROSTITUTES (false religions, heresies) AND OF THE ABOMINATIONS OF THE EARTH.”

Then a single powerful angel picked up a boulder like a great millstone and flung it into the sea, saying, “With such violence will Babylon the great city be hurled down [by the sudden, spectacular judgment of God], and will never again be found.
