Jeremiah 23:9 - Joseph Benson’s Commentary on the Old and New Testaments

My heart within me is broken This seems to be the beginning of a new discourse against the false prophets, with whom afterward the priests are joined. The first word of it in the Hebrew, לנבאים, is rendered by the Vulgate, Ad prophetas, To the prophets, as if it were the title of the following prophecy. In this Jeremiah describes the terror and concern which were upon him when he considered the horrible sin of these prophets in pretending a divine mission when they had received none, and in uttering as messages from God what were really their own inventions, and in direct opposition to every thing God had spoken. And he declares that, upon a view of their guilt, and of the evils they were bringing on themselves and their country, he was in trouble and agitation, like that of a man who had lost his reason through intoxication.
