1 Chronicles 21:23-26

23“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.”

24But 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!”

25So David gave Araunah 600 pieces of gold in payment for the threshing floor.

26David built an altar there to the Lord and sacrificed burnt offerings and peace offerings. And when David prayed, the Lord answered him by sending fire from heaven to burn up the offering on the altar.
