Leviticus 5:14-16

14The Lord said to Moses:

15“When anyone is unfaithful to the Lord by sinning unintentionally in regard to any of the Lord’s holy things, they are to bring to the Lord as a penalty a ram from the flock, one without defect and of the proper value in silver, according to the sanctuary shekel. It is a guilt offering.

16They must make restitution for what they have failed to do in regard to the holy things, pay an additional penalty of a fifth of its value and give it all to the priest. The priest will make atonement for them with the ram as a guilt offering, and they will be forgiven.
