37 But Ab'salom fled, and went to Talmai the son of Ammi'hud, king of Geshur. And David mourned for his son day after day. 38 So Ab'salom fled, and went to Geshur, and was there three years. 39 And the spirit of the king longed to go forth to Ab'salom; for he was comforted about 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.
