Leviticus 25:14

11 `A jubilee it [is], the fiftieth year, a year it is to you; ye sow not, nor reap its spontaneous growth, nor gather its separated things;

12 for a jubilee it [is], holy it is to you; out of the field ye eat its increase;

13 in the year of this jubilee ye turn back each unto his possession.

14 `And when thou sellest anything to thy fellow, or buyest from the hand of thy fellow, ye do not oppress one another;

15 by the number of years after the jubilee thou dost buy from thy fellow; by the number of the years of increase he doth sell to thee;

16 according to the multitude of the years thou dost multiply its price, and according to the fewness of the years thou dost diminish its price; for a number of increases he is selling to thee;

17 and ye do not oppress one another, and thou hast been afraid of thy God; for I [am] Jehovah your God.
