34 But Absalom fled. When the young man who kept watch looked up, he saw many people coming from the Horonaim road by the side of the mountain. 35 Jonadab said to the king, "See, the king's sons have come; as your servant said, so it has come about." 36 As soon as he had finished speaking, the king's sons arrived, and raised their voices and wept; and the king and all his servants also wept very bitterly. 37 But Absalom fled, and went to Talmai son of Ammihud, king of Geshur. David mourned for his son day after day. 38 Absalom, having fled to Geshur, stayed 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.
