2 Samuel 24:23-25

Revised Standard Version Catholic Edition

²³ All this, O king, Arau′nah gives to the king.” And Arau′nah said to the king, “The Lord your God accept you.” ²⁴ But the king said to Arau′nah, “No, but I will buy it of you for a price; I will not offer burnt offerings to the Lord my God which cost me nothing.” So David bought the threshing floor and the oxen for fifty shekels of silver. ²⁵ And David built there an altar to the Lord, and offered burnt offerings and peace offerings. So the Lord heeded supplications for the land, and the plague was averted from Israel.
