Revelation 18:2

And he cried mightily with a strong voice, saying, Babylon the great is fallen, is fallen, and is become the habitation of devils, and the hold of every foul spirit, and a cage of every unclean and hateful bird.

Ver. 2. And he cried mightily] So to awaken Babylon, that slept no less securely than that old Babylon, whose king Shesach was feasting and carousing in the bowls of the sanctuary, when the city was taken the same night. The people also did so little fear it, that it was three days after the city was taken by Cyrus ere some of them heard what was befallen them. (Herodot. Arist. Pol.)

Is fallen, is fallen] Certo, cito, penitus, or, with a double fall. They have fallen culpably, and shall fall penally. This was also long since foretold by Sibylla in the eighth book of her oracles:

" Και συ θριαμβος εση κοσμω, και αοιδος απαντων ".

" Tota eris in cineres quasi nunquam Roma fuisses. "

Rome (during the Roman felicity) was never taken but by the Gauls; but since it became pontifical, it hath been made a prey to all barbarous nations, and never besieged by any that took it not. There yet stands, near at hand, a second Babylon (saith Petrarch), cito itidem casura, si essetis viri. This would soon be down, if you would but stand up as men.

The habitation of devils] Which, by a sweet providence of God, for the good of mankind, are banished (as likewise fierce and wild beasts are) to deserts and unpopulated places. See Matthew 12:43. (It is an allusion to Isaiah 13:20; Isaiah 14:23; Jer 50:39) Yet not so, but that, by Divine permission, they haunt and pester the greatest throngs of people, yea, the holiest assemblies. Some take the words in another sense, thus, it is become a habitation of devils, that is, of idols; and this hath wrought her ruin. In the year 610, Boniface IV instituted the feast of All Saints, after that he had begged of the emperor the Pantheon of Rome, which he consecrated to the honour of All Saints, and set up the Virgin Mary in the place of Cybele, the mother of the gods. (Alsted. Chron.)
