And he cried mightily - Literally, “he cried with a strong great voice.” See Revelation 10:3.
Babylon the great is fallen, is fallen - See the notes on Revelation 14:8. The proclamation here is substantially the same as in that place, and no doubt the same thing is referred to.
And is become the habitation of devils - Of demons - in allusion to the common opinion that the demons inhabited abandoned cities, old ruins, and deserts. See the notes on Matthew 12:43-45. The language here is taken from the description of Babylon in Isaiah 13:20-22; and for a full illustration of the meaning, see the notes on that passage.
And the hold of every foul spirit - φυλακὴ phulakē. A watch-post, station, haunt of such spirits - That is, they, as it were, kept guard there; were stationed there; haunted the place.
And a cage of every unclean and hateful bird - That is, they would resort there, and abide there as in a cage. The word translated “cage” is the same which is rendered “hold” - φυλακὴ phulakē. In Isaiah 13:21, it is said, “and owls shall dwell there”; and in Isaiah 14:23, it is said that it would be a “possession for the bittern.” The idea is that of utter desolation; and the meaning here is, that spiritual Babylon - papal Rome Revelation 14:8 - will be reduced to a state of utter desolation resembling that of the real Babylon. It is not necessary to suppose this of the city of Rome itself - for that is not the object of the representation. It is the papacy, represented under the image of the city, and having its seat there. That is to be destroyed as utterly as was Babylon of old; that will become as odious, and loathsome, and detestable as the literal Babylon, the abode of monsters is.
