32 Jonadab , the son of Shimeah , David's brother , responded e , "Do not let my lord suppose they have put to death all the young men , the king's sons , for Amnon alone is dead ; because by the intent of Absalom this has been determined since the day that he violated 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.
