The LORD is Slow to Anger and Great in Power, Part 3

The Prophet again teaches us, that whatever he prophesied respecting the destruction of the city Nineveh, was for this end, — that God, by this remarkable evidence, might show that he had a care for his people, and that he was not unmindful of the covenant he had made with the children of Abraham. This prophecy would have otherwise produced no salutary effect on the Israelites; they might have thought that it was by chance, or by some fatal revolution, or through some other cause, that Nineveh had been overthrown. Hence the Prophet shows, that the ruin of the city, and of the monarchy of Nineveh, would be a proof of the paternal love of God towards his chosen people, and that such a change was to be made for the sake of one people, because God, though he had for a time punished the Israelites, yet purposed that some seed should remain, for it would have been inconsistent, that the covenant, which was to be inviolate, should be entirely abolished. We now then understand the Prophet’s object, and how this verse is to be connected with the rest of the context.…Heralds of peace shall ascend to the tops of mountains, that their voice might be more extensively heard…that there would be now free liberty to proclaim peace on the highest places. – John Calvin
