2 Samuel 24:24-25 NLT
But the king replied to Araunah, “No, I insist on buying it, for I will not present burnt offerings to the LORD my God that have cost me nothing.” So David paid him fifty pieces of silver for the threshing floor and the oxen.
David built an altar there to the LORD and sacrificed burnt offerings and peace offerings. And the LORD answered his prayer for the land, and the plague on Israel was stopped.
