William Burkitt on Revelation 17:15

Here the angel proceeds, and goes on farther in the explication of the vision. By the waters whereon the whore sat, he declares, are to be understood many and divers nations belonging to the Roman empire. Behold then of what church multitude is a note! Not of the church of Christ, his flock is a little flock; but of the antichristian synagogue which vaunts, that multitudes are on her side, The waters whereon the whore sat are multitudes, peoples, nations, and tongues. Alas, the multitude, or generality of persons, are prone to oppose that which is good, and those that do good.

Next, it is declared what instruments God will make use of as the executioners of this vengeance upon this great whore, the ten horns, that is, the ten kings which did before idolize her, and commit idolatry and spiritual whoredom with her, shall at length revolt from her, hate her, make her desolate, and naked, and shall eat her flesh, and burn her with fire.

Lord! what a strange, sudden, and mighty change, doth the power of converting grace make! Behold these ten kings, who sometimes doated upon the painted beauty of this great whore, when once their eyes shall be opened, their hearts will soon be alienated. Babylon's courts shall be crowded with suitors no longer; they shall make her desolate, by deserting her communion; make her naked, by withdrawing their former supplies afforded to her; they shall eat her flesh, feed themselves with spoils, and take her revenues to themselves; and burn her with fire, that is, shall utterly ruin and destroy her. The destruction of antichrist, once begun, shall hold on constantly, by degrees, till his final destruction.
