2. The royal city is to be demolished and deserted, v. 23. It shall be a possession for solitary frightful birds, particularly the bittern, joined with the cormorant and the owl, ch. xxiv. 11. And thus the utter destruction of the New-Testament Babylon is illustrated, Rev. xviii. 2. It has become a cage of every unclean and hateful bird. Babylon lay low, so that when it was deserted, and no care taken to drain the land, it soon became pools of water, standing noisome puddles, as unhealthful as they were unpleasant: and thus God will sweep it with the besom of destruction. When a people have nothing among them but dirt and filth, and will not be made clean with the besom of reformation, what can they expect but to be swept off the face of the earth with the besom of destruction?
