Leviticus 27:17-19

American Standard Version

¹⁷ If he sanctify his field from the year of jubilee, according to thy estimation it shall stand. ¹⁸ But if he sanctify his field after the jubilee, then the priest shall reckon unto him the money according to the years that remain unto the year of jubilee; and an abatement shall be made from thy estimation. ¹⁹ And if he that sanctified the field will indeed redeem it, then he shall add the fifth part of the money of thy estimation unto it, and it shall be assured to him.
