⁴⁹ or his uncle, or a son of his uncle, doth redeem him, or any of the relations of his flesh, of his family, doth redeem him, or -- his own hand hath attained -- then he hath been redeemed.

⁵⁰ `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.

⁵¹ `If yet many years, according to them he giveth back his redemption [money], from the money of his purchase.
