'Price' in the Bible

If the years [until the next Jubilee] are many, you shall increase the price, but if the years remaining are few, you shall reduce the price, because it is the number of crops that he is selling to you.

Then he [or his redeemer] shall calculate with his purchaser from the year when he sold himself to the purchaser to the Year of Jubilee, and the [original] price of his sale shall be adjusted according to the number of years. The time he was with his owner shall be considered as that of a hired man.
