2 Samuel 24:22-25

And Araunah said unto David, Let my lord the king take and offer up what seemeth good unto him: behold, here be oxen for burnt sacrifice, and threshing instruments and other instruments of the oxen for wood. All these things did Araunah, as a king, give unto the king. And Araunah said unto the king, The LORD thy God accept thee. And the king said unto Araunah, Nay; but I will surely buy it of thee at a price: neither will I offer burnt offerings unto the LORD my God of that which doth cost me nothing. So David bought the threshingfloor and the oxen for fifty shekels of silver. And David built there an altar unto the LORD, and offered burnt offerings and peace offerings. So the LORD was intreated for the land, and the plague was stayed from Israel.
