Leviticus 5:15-18

“If a person commits a breach of faith and sins unintentionally against the holy things of the LORD, then he shall bring his guilt offering to the LORD, a ram without blemish from the flock, valued by you in shekels of silver, that is, the shekel of the sanctuary, as a guilt offering. He shall make restitution for the sin which he has committed against the holy thing, and shall add a fifth [of the ram’s value] to it, and give it to the priest. The priest shall then make atonement for him with the ram of the guilt offering, and he shall be forgiven. “Now if anyone sins and does any of the things which the LORD has forbidden, though he was not aware of it, still he is guilty and shall bear his punishment. [Luke 12:48] He is then to bring to the priest a ram without blemish from the flock, according to your valuation, for a guilt offering. In this way the priest shall make atonement for him regarding the error which he committed unintentionally and did not know it, and he shall be forgiven.
