32 But just then Jonadab, the son of David's brother Shimea, arrived and said, "No, don't believe that all the king's sons have been killed! It was only Amnon! Absalom has been plotting this ever since Amnon raped his sister Tamar.

Matthew Henry's Commentary on 2 Samuel 13:32

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.
