'Price' in the Bible

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 the crops doth he sell unto thee.

And he shall reckon with him that bought him from the year that he sold himself to him unto the year of jubilee: and the price of his sale shall be according unto the number of years; according to the time of a hired servant shall he be with him.

If there be yet many years, according unto them he shall give back the price of his redemption out of the money that he was bought for.

And if there remain but few years unto the year of jubilee, then he shall reckon with him; according unto his years shall he give back the price of his redemption.
