Vayikra 25:15-17

Orthodox Jewish Bible

¹⁵ According to the number of shanim after the Yovel thou shalt buy of thy neighbor, and according unto the number of shanim of the tevuot (harvests, increases) he shall sell unto thee.

¹⁶ According to the multitude of shanim thou shalt increase the price thereof, and according to the fewness of shanim thou shalt diminish the price of it; for according to the number of the shanim of the tevuot doth he sell unto thee.

¹⁷ Ye shall not therefore take advantage of one another; but thou shalt fear Eloheicha: for I am Hashem Eloheichem.
