Leviticus 27:17-21

¹⁷If he gives his field from the year of Jubilee, the value will be fixed by your decision.

¹⁸But if he gives his field after the year of Jubilee, the amount of the money will be worked out by the priest in relation to the number of years till the coming year of Jubilee, and the necessary amount will be taken off your value.

¹⁹And if the man who has given the field has a desire to get it back, let him give a fifth more than the price at which it was valued and it will be his.

²⁰But if he has no desire to get it back, or if he has given it for a price to another man, it may not be got back again.

²¹But the field, when it becomes free at the year of Jubilee, will be holy to the Lord, as a field given under oath: it will be the property of the priest.
