Leviticus 27:19
And if the one who consecrated the field decides to redeem it, he must add a fifth to the assessed value, and it shall belong to him.
Berean Standard Bible
And if he that sanctified the field will in any wise redeem it, then he shall add the fifth part of the money of thy estimation unto it, and it shall be assured to him.
If he who dedicated the field will indeed redeem it, then he shall add the fifth part of the money of your valuation to it, and it shall remain his.
