2 Samuel 24:24-25
2 Samuel 24:24-25 AMP
But the king said to Araunah, “No, but I will certainly buy it from you for a price. I will not offer burnt offerings to the LORD my God which cost me nothing.” So David purchased the threshing floor and the oxen for fifty shekels of silver. David built an altar to the LORD there, and offered burnt offerings and peace offerings. So the LORD was moved [to compassion] by [David’s] prayer for the land, and the plague was held back from Israel.
