2 Samuel 13:21-33 - Absalom Kills Amnon
21 But when king David heard of all these things, he was very angry. 22 Absalom spoke to Amnon neither good nor bad; for Absalom hated Amnon, because he had forced his sister Tamar.
23 It happened after two full years, that Absalom had sheepshearers in Baal Hazor, which is beside Ephraim: and Absalom invited all the king's sons. 24 Absalom came to the king, and said, "See now, your servant has sheepshearers. Please let the king and his servants go with your servant."
25 The king said to Absalom, "No, my son, let us not all go, lest we be burdensome to you." He pressed him; however he would not go, but blessed him.
26 Then Absalom said, "If not, please let my brother Amnon go with us." The king said to him, "Why should he go with you?" 27 But Absalom pressed him, and he let Amnon and all the king's sons go with him.
28 Absalom commanded his servants, saying, "Mark now, when Amnon's heart is merry with wine; and when I tell you, 'Strike Amnon,' then kill him. Don't be afraid. Haven't I commanded you? Be courageous, and be valiant!" 29 The servants of Absalom did to Amnon as Absalom had commanded. Then all the king's sons arose, and every man got up on his mule, and fled.
30 It happened, while they were in the way, that the news came to David, saying, "Absalom has slain all the king's sons, and there is not one of them left!" 31 Then the king arose, and tore his garments, and lay on the earth; and all his servants stood by with their clothes torn.
32 Jonadab, the son of Shimeah, David's brother, answered, "Don't let my lord suppose that they have killed all the young men the king's sons; for Amnon only is dead; for by the appointment of Absalom this has been determined from the day that he forced his sister Tamar. 33 Now therefore don't let my lord the king take the thing to his heart, to think that all the king's sons are dead; for Amnon only is dead."
