You shall increase the price in proportion to a greater number of years, or decrease it in proportion to a lesser number of years; for he is selling you a given number of harvests.
Jewish Publication Society of America Version (JPS1917) - Leviticus 25:16 >According to the multitude of the years thou shalt increase the price thereof, and according to the fewness of the years thou shalt diminish the price of it; for the number of crops doth he sell unto thee.
