28 Absalom commanded his servants , saying , "See now , when Amnon's heart is merry with wine , and when I say to you, 'Strike Amnon ,' then put him to death . Do not fear ; have not I myself commanded you? Be courageous and be valiant e ." 29 The servants of Absalom did to Amnon just as Absalom had commanded . Then all the king's sons arose and each mounted his mule and fled .
30 Now it was while they were on the way that the report came to David , saying , "Absalom has struck down all the king's sons , and not one of them is left ." 31 Then the king arose , tore his clothes and lay on the ground ; and all his servants were standing by with clothes torn . 32 Jonadab , the son of Shimeah , David's brother , responded e , "Do not let my lord suppose they have put to death all the young men , the king's sons , for Amnon alone is dead ; because by the intent of Absalom this has been determined since the day that he violated his sister Tamar . 33 "Now therefore, do not let my lord the king take the report to heart , namely , 'all the king's sons are dead ,' for only Amnon is dead ." 34 Now Absalom had fled . And the young man who was the watchman raised his eyes and looked , and behold , many people were coming from the road behind him by the side of the mountain . 35 Jonadab said to the king , "Behold , the king's sons have come ; according to your servant's word , so it happened ." 36 As soon as he had finished speaking , behold , the king's sons came and lifted their voices and wept ; and also the king and all his servants wept very bitterly e . 37 Now Absalom fled and went to Talmai the son of Ammihud , the king of Geshur . And David mourned for his son every day . 38 So Absalom had fled and gone to Geshur , and was there three years .

Commentary on 2 Samuel 13:21-29
(Read 2 Samuel 13:21-29)
Observe the aggravations of Absalom's sin: he would have Ammon slain, when least fit to go out of the world. He engaged his servants in the guilt. Those servants are ill-taught who obey wicked masters, against God's commands. Indulged children always prove crosses to godly parents, whose foolish love leads them to neglect their duty to God.
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.
