2 Samuel 24:24-25 Tree of Life Version (TLV)
24 But the king said to Araunah, “No, but I will surely buy it from you at a price. I will not offer burnt offerings to Adonai my God that cost me nothing.” So David bought the threshing floor and the oxen for 50 shekels of silver. 25 Then David built there an altar to Adonai, and offered burnt offerings and fellowship offerings. So Adonai was moved by prayer of entreaty for the land, and restrained the plague from Israel.
