2 Samuel 14:4, 22

Now when the woman of Tekoa spoke to the king, she fell on her face to the ground and prostrated herself and said, “Help, O king.”

Joab fell on his face to the ground, prostrated himself and blessed the king; then Joab said, “Today your servant knows that I have found favor in your sight, O my lord, the king, in that the king has performed the request of his servant.”
