2 Samuel 13:24-28

24And Absalom came to the king and said, "Behold, your servant has sheepshearers. Please let the king and his servants go with your servant."

25But the king said to Absalom, "No, my son, let us not all go, lest we be burdensome to you." He pressed him, but he would not go but gave him his blessing.

26Then Absalom said, "If not, please let my brother Amnon go with us." And the king said to him, "Why should he go with you?"

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

28Then Absalom commanded his servants, "Mark when Amnon's heart is merry with wine, and when I say to you, 'Strike Amnon,' then kill him. Do not fear; have I not commanded you? Be courageous and be valiant."
