Leviticus 27:17-24
If he consecrates his field during the Year of Jubilee, the price will stand according to your assessment.But if he consecrates his field after the Jubilee, the priest will calculate the price for him in proportion to the years left until the next Year of Jubilee, so that your assessment will be reduced.If the one who consecrated the field decides to redeem it, he must add a fifth to the assessed value, and the field will transfer back to him.But if he does not redeem the field or if he has sold it to another man, it is no longer redeemable.When the field is released in the Jubilee, it will be holy to the Lord like a field permanently set apart; it becomes the priest’s property.“ If a person consecrates to the Lord a field he has purchased that is not part of his inherited landholding,then the priest will calculate for him the amount of the assessment up to the Year of Jubilee, and the person will pay the assessed value on that day as a holy offering to the Lord.In the Year of Jubilee the field will return to the one he bought it from, the original owner.
