1 Chronicles 21:22-24

David said to Araunah, “Let me buy this threshing floor from you at its full price. Then I will build an altar to the LORD there, so that he will stop the plague.” “Take it, my lord the king, and use it as you wish,” Araunah said to David. “I will give the oxen for the burnt offerings, and the threshing boards for wood to build a fire on the altar, and the wheat for the grain offering. I will give it all to you.” But King David replied to Araunah, “No, I insist on buying it for the full price. I will not take what is yours and give it to the LORD. I will not present burnt offerings that have cost me nothing!”
