After these things I saw another angel come down from heaven, having great power; and the earth was lighted by his glory. And he cried with a mighty voice, saying Babylon the Great is fallen and has become a habitation of those possessed with devils and the shelter of every foul spirit and the shelter of every unclean and detestable bird and the shelter of every unclean and loathsome wild beast. Because all the nations have drunk of the wine of her wrath and the kings of the earth have committed adultery with her and the merchants of the earth have become rich through the power of her trade.
And I heard another voice out of heaven saying Come out of her, O my people, so that you may not become partakers of her sins and lest you be smitten by her plagues. For her sins have reached up to heaven and God has remembered her iniquities.
Reward her even as she has rewarded you, and return to her a double portion according to her works; in the cup which she has mixed, mix for her double. For as much as she has glorified herself and lived deliciously, give her so much torment and sorrow; for she says in her heart, I sit a queen, and am no widow and shall see no sorrows. Therefore her plagues shall come in one day, death and mourning and famine, and she shall be burned with fire; for mighty is the Lord God who judges her. And the kings of the earth who committed adultery and lived deliciously with her will weep and mourn and wail over her when they see the smoke of her burning. Standing afar off for the fear of her torment, saying, Woe, woe, that great city Babylon, that mighty city! For in one hour you have been condemned....
