2 Samuel 24:22-25

Araunah said to David, “My master and king, you may take anything you want for a sacrifice. Here are some oxen for the whole burnt offering and the threshing boards and the yokes for the wood. My king, I give everything to you.” Araunah also said to the king, “May the LORD your God be pleased with you.” But the king answered Araunah, “No, I will pay you for the land. I won’t offer to the LORD my God burnt offerings that cost me nothing.” So David bought the threshing floor and the oxen for one and one-fourth pounds of silver. He built an altar to the LORD there and offered whole burnt offerings and fellowship offerings. Then the LORD answered his prayer for the country, and the disease in Israel stopped.
