And shall say unto them, Thus says the LORD of hosts; Even so will I break this people and this city, as one breaks a potter's vessel, that cannot be made whole again: and they shall bury them in Topheth, till there be no place to bury.
Read Chapter 19
Augustine of Hippo
Notice here “the rod of direction” that is described. “You have loved righteousness and hated iniquity.” Draw near to that “rod.” Let Christ be your King: let him rule you with that rod, not crush you with it. For that rod is “a rod of iron,” an inflexible rod. “You shall rule them with a rod of iron and break them in pieces like a potter’s vessel.” Some he rules; others he “breaks in pieces.” He “rules” those who are spiritual; he “breaks in pieces” those who are concerned about earthly desires.… Would he so loudly declare that he was about to strike you if he really wanted to strike you? He is, then, holding back his hand from the punishment of your offenses; but you dare not hold back. Turn around and face the punishment for your offenses, for there can be no unpunished offenses. Punishment therefore must be executed either by you or by him. You should plead guilty then in order that he may grant you a reprieve. - "Expositions of the Psalms 45.16"
