II Samuel 24:21

21 Araunah said, "Why has my lord the king come to his servant?" "To buy your threshing floor," David answered, "so I can build an altar to the Lord, that the plague on the people may be stopped."

21 And Araunah said, Why has my lord the king come to his servant? And David said, To give you a price for your grain-floor, so that I may put up an altar to the Lord, and the disease may be stopped among the people.
