2 Samuel 13:26

22 And Absalom never said a word to Amnon, either good or bad, because he hated Amnon for disgracing his sister Tamar.

23 Two years later, when Absalom’s sheepshearers were at Baal-hazor near Ephraim, he invited all the sons of the king.

24 And he went to the king and said, “Your servant has just hired shearers. Will the king and his servants please come with me?”

25 “No, my son,” the king replied, “we should not all go, or we would be a burden to you.” Although Absalom urged him, he was not willing to go, but gave him his blessing.

26 “If not,” said Absalom, “please let my brother Amnon go with us.” “Why should he go with you?” the king asked.

27 But Absalom urged him, so the king sent Amnon and the rest of his sons.

28 Now Absalom had ordered his young men, “Watch Amnon until his heart is merry with wine, and when I order you to strike Amnon down, you are to kill him. Do not be afraid. Have I not commanded you? Be courageous and valiant!”

29 So Absalom’s young men did to Amnon just as Absalom had ordered. Then all the other sons of the king got up, and each one fled on his mule.

30 While they were on the way, a report reached David: “Absalom has struck down all the sons of the king; not one of them is left!”
