Leviticus 5:6, 13, 16

he shall bring to the LORD as his compensation for the sin that he has committed, a female from the flock, a lamb or a goat, for a sin offering. And the priest shall make atonement for him for his sin.

Thus the priest shall make atonement for him for the sin which he has committed in any one of these things, and he shall be forgiven. And the remainder shall be for the priest, as in the grain offering.”

He shall also make restitution for what he has done amiss in the holy thing and shall add a fifth to it and give it to the priest. And the priest shall make atonement for him with the ram of the guilt offering, and he shall be forgiven.
