1 Chronicles 21:23-26

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.”

25So David gave Ornan 600 shekels of gold by weight for the site.

26Then David built an altar to the Lord there and presented burnt offerings and peace offerings. And he called on the Lord, and He answered him with fire from heaven on the altar of burnt offering.
