'Bought' in the Bible

but the poor man had nothing at all, but one little ewe lamb which he had bought, and was nourishing; and it grew up with him, and together with his children: it ate of his morsel, and drank of his own cup, and slept in his bosom, and was to him as a daughter.

And the king said to Araunah, No; but I will in any case buy them of thee at a price: neither will I offer up to Jehovah my God burnt-offerings without cost. And David bought the threshing-floor and the oxen for fifty shekels of silver.
