Revelation chapter 17 summary: A woman arrayed in purple and scarlet, with a golden cup in her hand sits upon the beast; which is great Babylon, the mother of all abominations. The interpretation of the seven heads; and the ten horns. The victory of the Lamb. The punishment of the whore. Revelation chapter 18 summary: Babylon is fallen. People commanded to depart out of her. The kings of the earth, with the merchants and mariners, lament over her. The saints rejoice for the judgments of God upon her.
