Leviticus 5:15-16

15“If someone offends by sinning unintentionally in regard to any of the Lord’s holy things, he must bring his penalty for guilt to the Lord: an unblemished ram from the flock (based on your assessment of its value in silver shekels, according to the sanctuary shekel) as a guilt offering.

16He is to make restitution for his sin regarding any holy thing, adding a fifth of its value to it, and give it to the priest. Then the priest will make atonement on his behalf with the ram of the guilt offering, and he will be forgiven.
