2 Samuel 14:21-22

21And the king said to Joab, “All right, I have granted this thing. Go therefore, bring back the young man Absalom.”

22Then Joab fell to the ground on his face and bowed himself, and thanked the king. And Joab said, “Today your servant knows that I have found favor in your sight, my lord, O king, in that the king has fulfilled the request of his servant.”
