And when a man doth eat of a holy thing through ignorance, then he hath added its fifth part to it, and hath given it to the priest, with the holy thing;
Leviticus 27:13
and if he really redeem it, then he hath added its fifth to thy valuation.
Leviticus 27:15
and if he who is sanctifying doth redeem his house, then he hath added a fifth of the money of thy valuation to it, and it hath become his.
Leviticus 5:15-19
When a person committeth a trespass, and hath sinned through ignorance against the holy things of Jehovah, then he hath brought in his guilt-offering to Jehovah, a ram, a perfect one, out of the flock, at thy valuation in silver -- shekels by the shekel of the sanctuary -- for a guilt-offering.
