'Babylon the Great' in the Bible

Then a second angel followed, crying, "Fallen, fallen is Babylon the Great, Who has made all the nations drink the wine Of the frenzy of her fornication."

Upon her forehead a name was written, a mystery, "BABYLON THE GREAT, THE MOTHER OF HARLOTS, AND ABOMINABLE THINGS OF THE EARTH."

He shouted with a mighty cry, saying. "She is fallen! She is fallen, Babylon the great! Now she is a dwelling-place of demons, A stronghold of every foul spirit, A stronghold of every foul and hateful bird.
