Leviticus 27:19-21

New Century Version

¹⁹ If the person who gave the field wants to buy it back, one-fifth must be added to that price, and the field will belong to the first owner again.

²⁰ “‘If the person does not buy back the field, or if it is sold to someone else, the first person cannot ever buy it back. ²¹ When the land is released at the year of Jubilee, it will become holy to the Lord, like land specially given to him. It will become the property of the priests.
