Leviticus 27:23-25

King James Version

²³ Then the priest shall reckon unto him the worth of thy estimation, even unto the year of the jubile: and he shall give thine estimation in that day, as a holy thing unto the Lord.

²⁴ In the year of the jubile the field shall return unto him of whom it was bought, even to him to whom the possession of the land did belong.

²⁵ And all thy estimations shall be according to the shekel of the sanctuary: twenty gerahs shall be the shekel.
