2 Samuel 14:21-22

21Then the king said to Joab, “Listen, I will most certainly do this thing; now go, bring back the young man Absalom.”

22Joab bowed his face toward the ground and lay himself down and blessed the king. Then Joab said, “Today your servant knows that I have found favor in your sight, my lord, O king, in that the king has done the request of his servant.”
