1 Chronicles 21:23-24

23Ornan said to David, “Take it for yourself; and let my lord the king do what is good in his eyes. See, I will give you the oxen also for burnt offerings and the threshing sledges (heavy wooden platforms) for wood and the wheat for the grain offering; I give it all.”

24But King David said to Ornan, “No, I will certainly pay the full price; for I will not take what is yours for the Lord, nor offer a burnt offering which costs me nothing.”
