1. God will take this work of punishing Jerusalem into his own hands; and who knows the power of his anger and what a fearful thing it is to fall into his hands? Observe what a strong emphasis is laid upon it (v. 8): I, even I, am against thee. God had been for Jerusalem, to defend and save it; but miserable is its case when he has turned to be its enemy and fights against it. If God be against us, the whole creation is at war with us, and nothing can be for us so as to stand us in any stead: "You think it is only the Chaldean army that is against you, but they are God's hand, or rather the staff in his hand; it is I, even I, that am against thee, not only to speak against thee by prophets, but to act against thee by providence. I will execute judgments in thee (v. 10), in the midst of thee (v. 8), not only in the suburbs, but in the heart of the city, not only in the borders, but in the bowels of the country." Note, Those who will not observe the judgments of God's mouth shall not escape the judgments of his hand; and God's judgments, when they come with commission, will penetrate into the midst of a people, will enter into the soul, into the bowels like water and like oil into the bones. I will execute judgments. Note, God himself undertakes to execute his own judgments, according to the true and full intent of them; whatever are the instruments, he is the principal agent.
