'Buyer' in the Bible

and if it is not redeemed until the fulness to him of a perfect year, then hath the house which is in a walled city been established to extinction to the buyer of it, to his generations; it goeth not out in the jubilee;

'And he hath reckoned with his buyer from the year of his being sold to him till the year of jubilee, and the money of his sale hath been by the number of years; as the days of an hireling it is with him.
