1 Chronicles 21:22-24

Then David said to Ornan, “Give me the site of this threshing floor, that I may build on it an altar to the LORD; for the full price you shall give it to me, that the plague may be restrained from the people.” Ornan said to David, “Take it for yourself; and let my lord the king do what is good in his sight. See, I will give the oxen for burnt offerings and the threshing sledges for wood and the wheat for the grain offering; I will give it all.” But 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, or offer a burnt offering which costs me nothing.”
