Leviticus 5:14-16

Then the LORD spoke to Moses, saying: “If a person commits a trespass, and sins unintentionally in regard to the holy things of the LORD, then he shall bring to the LORD as his trespass offering a ram without blemish from the flocks, with your valuation in shekels of silver according to the shekel of the sanctuary, as a trespass offering. And he shall make restitution for the harm that he has done in regard to the holy thing, and shall add one-fifth to it and give it to the priest. So the priest shall make atonement for him with the ram of the trespass offering, and it shall be forgiven him.
