1 Chronicles 21:23-24

Then Ornan said to David, “Take it, and let my lord the king do what seems good to him. See, I give the oxen for burnt offerings and the threshing sledges for the wood and the wheat for a grain offering; I give it all.” But King David said to Ornan, “No, but I will buy them for the full price. I will not take for the LORD what is yours, nor offer burnt offerings that cost me nothing.”
