2 Samuel 13:26-28

Then Absalom said, “If not, then at least let my brother Amnon go with us.” And the king said to him, “Why should he go with you?” But Absalom urged him [again], and he let Amnon and all the king’s sons go with him. Now Absalom commanded his servants, “Notice carefully, when Amnon’s heart is joyous with wine, and when I say to you, ‘Strike Amnon,’ then kill him. Do not be afraid; have I not commanded you myself [and in doing so have I not taken full responsibility for his death]? Be courageous and brave.”
