2 Samuel 13:26-28

Then Absalom said, “If not, please let my brother Amnon go with us.” And the king said to him, “Why should he go with you?” But when Absalom urged him, he let Amnon and all the king’s sons go with him. Absalom commanded his servants, saying, “See now, when Amnon’s heart is merry with wine, and when I say to you, ‘Strike Amnon,’ then put him to death. Do not fear; have not I myself commanded you? Be courageous and be valiant.”
