Leviticus 27:21-24

When the field is released in the Year of Jubilee, it will be holy, a field specially set apart for the LORD. It will become the property of the priests. “If someone dedicates to the LORD a field he has purchased but which is not part of his family property, the priest will assess its value based on the number of years left until the next Year of Jubilee. On that day he must give the assessed value of the land as a sacred donation to the LORD. In the Year of Jubilee the field must be returned to the person from whom he purchased it, the one who inherited it as family property.
