Leviticus 27:18-20

New Catholic Bible

¹⁸ But if he sets apart the field after the Jubilee Year, the priest shall determine the value according to the number of years remaining until the Jubilee Year, and thus the evaluation shall be adjusted. ¹⁹ If he wishes to redeem the field that he had set apart, then he shall add a fifth to your evaluation and it shall be his. ²⁰ But if he does not redeem the field, or if he sold the field to another person, then it is not to be redeemed anymore,
