'Bought' in the Bible

but the poor man had nothing except one small ewe lamb that he had bought. He raised it, and it grew up, living with him and his children. It shared his meager food and drank from his cup; it slept in his arms, and it was like a daughter to him.

The king answered Araunah, “No, I insist on buying it from you for a price, for I will not offer to the Lord my God burnt offerings that cost me nothing.” David bought the threshing floor and the oxen for 20 ounces of silver.
