Leviticus 25:16

When the years are many, you are to increase the price, and when the years are few, you are to decrease the price, because what he is really selling you is the number of crops.

(New International Version)

'In proportion to the extent of the years you shall increase its price, and in proportion to the fewness of the years you shall diminish its price, for it is a number of crops he is selling to you.

(New American Standard Bible)

According to the multitude of years thou shalt increase the price thereof, and according to the fewness of years thou shalt diminish the price of it: for according to the number of the years of the fruits doth he sell unto thee.

(King James Version)
