'Prostrating' in the Bible

When the woman from Tekoa spoke to the king, she fell on her face to the ground, prostrating herself to address him, "Help, your majesty!"

At this, Joab fell on his face to the ground, prostrating himself to bless the king, and then said, "Today your servant realizes that he's found favor with you, your majesty, in that the king has acted on the request of his servant."
