2 Samuel 14:22

Joab fell facedown in homage and blessed the king. “Today,” said Joab, “your servant knows that he has found favor in your eyes, my lord the king, because the king has granted his request.”

And Joab fell to the ground on his face, and bowed himself, and thanked the king: and Joab said, To day thy servant knoweth that I have found grace in thy sight, my lord, O king, in that the king hath fulfilled the request of his servant.
