Jeremiah 4:9 - Joseph Benson’s Commentary on the Old and New Testaments

At that day the heart of the king shall perish Both his wisdom and his courage: despairing of success, he shall have no spirit to do any thing, and if he had, he would be at a loss what to do; and the heart of the princes His privy counsellors, who ought to animate and advise him, shall be as much at a loss, and as much in despair as he. And the priests shall be astonished Shall be in such a consternation that they shall have no heart to execute their office, and therefore not likely to put spirit into the people. The prophets shall wonder The false prophets, that had nothing but visions of peace for them, shall be thrown into the greatest amazement imaginable, seeing their own guilty blood ready to be shed by that sword, of which they had frequently told the people there was no danger.
