37 But Absalom fled, and went to Talmai the son of Ammihur, king of Geshur. David mourned for his son every day. 38 So Absalom fled, and went to Geshur, and was there three years. 39 the soul of king David longed to go forth to Absalom: for he was comforted concerning Amnon, seeing he was dead.

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.
