2 Samuel 13:21-33 - Absalom Kills Amnon
21 And king David heard of all these things and was very wroth. 22 And Absalom said unto his brother Amnon neither good nor bad. Howbeit, Absalom hated Amnon because he had forced his sister Tamar.
23 And it happened, two year after, that Absalom had a sheep shearing in Baal Hazor besides the tribe of Ephraim, and bade all the king's sons. 24 And he came to the king and said, "Behold, thy servant hath a sheep shearing. Let the king and his servants come with thy servant."
25 And the king said unto Absalom, "Oh nay my son let us not go every one of us that we be not chargeable unto thee." And Absalom lay sore upon him: howbeit, he would not go, but blessed him.
26 Then said Absalom, "Then let my brother Amnon go with us." And the king answered, "What needeth it that he go with thee?" 27 But Absalom made such insistence that he let Amnon go with him, and all the king's children.
28 Then Absalom commanded his young men, saying, "Mark when Amnon's heart is merry with wine; and when I bid you smite Amnon, then kill him. Fear not, for it is I that bid you. Be bold therefore and play the lusty bloods." 29 And the young men of Absalom served Amnon even as Absalom commanded them. And all the king's sons arose and took each man his mule and fled.
30 And while they were yet in the way, tidings came to David that Absalom had slain all the king's sons, so that none was left alive. 31 Then the king arose and tare his garments and lay along on the earth: and all his servants stood by with their clothes rent.
32 Then Jonadab the son of Shimeah David's brother answered and said, "Let not my lord suppose that they have slain all the young men, the king's sons: save Amnon only is dead. For that hath been ever in Absalom's mouth since he forced his sister Tamar. 33 Now therefore let not my lord the king take the thing so grievously to think that all the king's sons were dead, when Amnon only is dead."
