Leviticus 27:23-25

Young's Literal Translation

²³ then hath the priest reckoned to him the amount of thy valuation unto the year of jubilee, and he hath given thy valuation in that day -- a holy thing to Jehovah;

²⁴ in the year of the jubilee the field returneth to him from whom he bought it, to him whose [is] the possession of the land.

²⁵ And all thy valuation is by the shekel of the sanctuary: twenty gerahs is the shekel.
