Leviticus 27:18-23

18But if they dedicate a field after the Jubilee, the priest will determine the value according to the number of years that remain until the next Year of Jubilee, and its set value will be reduced. 19If the one who dedicates the field wishes to redeem it, they must add a fifth to its value, and the field will again become theirs. 20If, however, they do not redeem the field, or if they have sold it to someone else, it can never be redeemed. 21When the field is released in the Jubilee, it will become holy, like a field devoted to the Lord; it will become priestly property. 22“ ‘If anyone dedicates to the Lord a field they have bought, which is not part of their family land, 23the priest will determine its value up to the Year of Jubilee, and the owner must pay its value on that day as something holy to the Lord.
