Leviticus 25:27 Then let him count the years of the
sale thereof, and restore the overplus unto the man to whom he sold it; that he may return unto his possession.
Leviticus 25:50 And he shall reckon with him that bought him from the year that he was sold to him unto the year of jubilee; and the price of his
sale shall be according unto the number of years, according to the time of a hired servant shall it be with him.
