Leviticus 5:14-19

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. “If a person sins, and commits any of these things which are forbidden to be done by the commandments of the LORD, though he does not know it, yet he is guilty and shall bear his iniquity. And he shall bring to the priest a ram without blemish from the flock, with your valuation, as a trespass offering. So the priest shall make atonement for him regarding his ignorance in which he erred and did not know it, and it shall be forgiven him. It is a trespass offering; he has certainly trespassed against the LORD.”
