2 Samuel 13:23-29

23And it came to pass after two full years, that Absalom had sheepshearers in Baal-Hazor, which is beside Ephraim; and Absalom invited all the king's sons.

24And Absalom came to the king, and said, Behold, now, thy servant has sheepshearers; let the king, I pray thee, and his servants go with thy servant.

25And the king said to Absalom, No, my son, let us not all go, lest we be burdensome to thee. And he urged him, but he would not go; and he blessed him.

26And Absalom said, If not, I pray thee, let my brother Amnon go with us. And the king said to him, Why should he go with thee?

27But Absalom pressed him; and he let Amnon and all the king's sons go with him.

28And Absalom commanded his servants, saying, Mark ye now when Amnon's heart is merry with wine, and when I say to you, Smite Amnon; then slay him, fear not: have not I commanded you? be courageous, and be valiant.

29And the servants of Absalom did to Amnon as Absalom had commanded. Then all the king's sons arose, and they rode each upon his mule and fled.
