1 Chronicles 21:24-27

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.” So David gave Ornan 600 shekels of gold by weight for the site. Then David built an altar to the LORD there and offered burnt offerings and peace offerings. And he called to the LORD and He answered him with fire from heaven on the altar of burnt offering. The LORD commanded the angel, and he put his sword back in its sheath.
