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.
“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.
They are to bring to the priest as a guilt offering a ram from the flock, one without defect and of the proper value. In this way the priest will make atonement for them for the wrong they have committed unintentionally, and they will be forgiven.
It is a guilt offering; they have been guilty of wrongdoing against the LORD.”
