30 While they were on the way, news came to David, "Absalom has struck down all the king's sons, and not one of them is left." 31 Then the king arose and tore his garments and lay on the earth. And all his servants who were standing by tore their garments. 32 But Jonadab the son of Shimeah, David's brother, said, "Let not my lord suppose that they have killed all the young men, the king's sons, for Amnon alone is dead. For by the command of Absalom this has been determined from the day he violated his sister Tamar. 33 Now therefore let not my lord the king so take it to heart as to suppose that all the king's sons are dead, for Amnon alone is dead." 34 But Absalom fled. And the young man who kept the watch lifted up his eyes and looked, and behold, many people were coming from the road behind him[1] by the side of the mountain. 35 And Jonadab 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 Absalom fled and went to Talmai the son of Ammihud, king of Geshur. And David mourned for his son day after day. 38 So Absalom fled and went to Geshur, and was there three years. 39 And the spirit of the king[2] longed to go out[3] to Absalom, because he was comforted about Amnon, since 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.
