2 Samuel 24:20-21

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

21Then Araunah said, “Why has my lord the king come to his servant?” And David said, “To buy the threshing floor from you, in order to build an altar to the Lord, 1that the plague may be held back from the people.”
