Leviticus 5:10, 13, 16, 18

The second [bird] he shall prepare as a burnt offering, according to the ordinance. So the priest shall make atonement on his behalf for the sin which he has committed, and it will be forgiven him.

In this way the priest shall make atonement for him for the sin which he has committed in one of these things, and it will be forgiven him; then the rest shall be for the priest, like the grain 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.

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.
