34 But Ab'salom fled. And the young man who kept the watch lifted up his eyes, and looked, and behold, many people were coming from the Horona'im road by the side of the mountain. 35 And Jon'adab said to the king, "Behold, the king's sons have come; as your servant said, so it has come about." 36 And as soon as he had finished speaking, behold, the king's sons came, and lifted up their voice and wept; and the king also and all his servants wept very bitterly. 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.

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.
