King James Version
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.English Standard Version
If the years are many, you shall increase the price, and if the years are few, you shall reduce the price, for it is the number of the crops that he is selling to you.New International Version
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.
