Leviticus 27:19

19 If he who sanctified the field will indeed redeem it, then he shall add the fifth part of the money of your estimation to it, and it shall be assured to him.

Leviticus 27:19 In-Context

17 If he sanctify his field from the year of jubilee, according to your estimation it shall stand.
18 But if he sanctify his field after the jubilee, then the priest shall reckon to him the money according to the years that remain to the year of jubilee; and an abatement shall be made from your estimation.
19 If he who sanctified the field will indeed redeem it, then he shall add the fifth part of the money of your estimation to it, and it shall be assured to him.
20 If he will not redeem the field, or if he has sold the field to another man, it shall not be redeemed any more:
21 but the field, when it goes out in the jubilee, shall be holy to Yahweh, as a field devoted; the possession of it shall be the priest's.
