Adam Clarke on Revelation 18:8

Therefore shall her plagues come - Death, by the sword of her adversaries; mourning on account of the slaughter; and famine, the fruits of the field being destroyed by the hostile bands.

Utterly burned with fire - Of what city is this spoken? Rome pagan has never been thus treated; Alaric and Totilas burnt only some parts with fire. Rome papal has not been thus treated; but this is true of Jerusalem, and yet Jerusalem is not generally thought to be intended.
