Leviticus 27:16-21

¹⁶If you dedicate some of your land to the Lord, then its value shall be determined by the amount of seed required to sow it: fifty shekels of silver for every homer of barley seed used.

¹⁷If you dedicate your field during the Jubilee Year, the value will be the full amount calculated.

¹⁸But if you dedicate your field after the Jubilee, the priest will work out the value depending on the number of years left until the next Jubilee Year, so reducing the value.

¹⁹But if you want to buy your field back, you have to add one fifth to its value in payment. Then it will belong to you again.

²⁰But if you don't buy the field back, or if you've already sold it to someone else, it can't ever be bought back.

²¹When the Jubilee comes, the field will become holy, in the same way as a field devoted to the Lord. It will become the property of the priests.
