I. Desolating judgments are here summoned, v. 9. The sheep of God's pasture are now to be made the sheep of his slaughter, to fall as victims to his justice, and therefore the beasts of the field and the forest are called to come and devour. They are beasts of prey, and do it from their own ravenous disposition; but God permits them to do it, nay, he employs them as his servants in doing it, the ministers of his justice, though they mean not so, neither does their heart think so. If this refers primarily to the descent made upon them by the Babylonians, and their devouring them, yet it may look further, to the destruction of Jerusalem and the Jewish nation by the Romans, after these outcasts of them (mentioned v. 8) were gathered in to the Christian church. The Roman armies came upon them as beasts of the forest to devour them, and they quite took away their place and nation. Note, When God has bloody work to do he has beasts of prey within call, to be employed in doing it.
