Leviticus 5:15-17 New International Version - UK (NIVUK)
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.[a] It is a guilt offering. 16 They 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.
17 ‘If anyone sins and does what is forbidden in any of the Lord’s commands, even though they do not know it, they are guilty and will be held responsible.
