36 And it cometh to pass at his finishing to speak, that lo, the sons of the king have come, and they lift up their voice, and weep, and also the king and all his servants have wept—a very great weeping.

Matthew Henry's Commentary on 2 Samuel 13:36

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.
