I Chronicles 21:23-24

But Ornan said to David, “Take it to yourself, and let my lord the king do what is good in his eyes. Look, I also give you the oxen for burnt offerings, the threshing implements for wood, and the wheat for the grain offering; I give it all.” Then King David said to Ornan, “No, but I will surely buy it for the full price, for I will not take what is yours for the LORD, nor offer burnt offerings with that which costs me nothing.”
