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.
30, 31. tidings came to David, saying, Absalom hath slain all the king's sons—It was natural that in the consternation and tumult caused by so atrocious a deed, an exaggerated report should reach the court, which was at once plunged into the depths of grief and despair. But the information of Jonadab, who seems to have been aware of the plan, and the arrival of the other princes, made known the real extent of the catastrophe.
