'Babylon the Great' in the Bible

The king reflected and said, ‘Is this not Babylon the great, which I myself have built as a royal residence by the might of my power and for the glory of my majesty?’

And another angel, a second one, followed, saying, “Fallen, fallen is Babylon the great, she who has made all the nations drink of the wine of the passion of her immorality.”

The great city was split into three parts, and the cities of the nations fell. Babylon the great was remembered before God, to give her the cup of the wine of His fierce wrath.

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

And he cried out with a mighty voice, saying, “Fallen, fallen is Babylon the great! She has become a dwelling place of demons and a prison of every unclean spirit, and a prison of every unclean and hateful bird.
