'Bought' in the Bible

but the poor man had nothing, save one little ewe lamb, which he had bought and nourished up: and it grew up together with him, and with his children; it did eat of his own morsel, and drank of his own cup, and lay in his bosom, and was unto him as a daughter.

And the king said unto Araunah, Nay; but I will verily buy it of thee at a price. Neither will I offer burnt-offerings unto Jehovah my God which cost me nothing. So David bought the threshing-floor and the oxen for fifty shekels of silver.
