Leviticus 27:22-24

22If he dedicates to the Lord a field that he has bought, which is not a part of his possession,

23then the priest shall calculate the amount of the valuation for it up to the year of jubilee, and the man shall give the valuation on that day as a holy gift to the Lord.

24In the year of jubilee the field shall return to him from whom it was bought, to whom the land belongs as a possession.
