2 Samuel 24:20-21

20Araunah looked down and saw the king and his servants crossing over toward him; and he went out and bowed before the king with his face toward the ground.

21Araunah said, “Why has my lord the king come to his servant?” And David said, “To buy the threshing floor from you, to build an altar to the Lord, so that the plague may be held back from the people.”
