30 While they were on the way, news came to David, "Absalom has struck down all the king's sons, and not one of them is left."

Matthew Henry's Commentary on 2 Samuel 13:30

Commentary on 2 Samuel 13:30-39

(Read 2 Samuel 13:30-39)

Jonadab was as guilty of Ammon's death, as of his sin; such false friends do they prove, who counsel us to do wickedly. Instead of loathing Absalom as a murderer, David, after a time, longed to go forth to him. This was David's infirmity: God saw something in his heart that made a difference, else we should have thought that he, as much as Eli, honoured his sons more than God.
