34 And Absalom fled. And the young man that watched lifted up his eyes and looked, and behold, there came much people from the way behind him, from the hill-side. 35 And Jonadab said to the king, Behold, the king's sons come: as thy servant said, so it is. 36 And as soon as he had ended 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 And Absalom fled, and went to Talmai, the son of Ammihud, king of Geshur. And [David] mourned for his son every day. 38 Now Absalom 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.
