Numbers 5:6-8

6“Say to the Israelites: ‘Any man or woman who wrongs another in any way and so is unfaithful to the Lord is guilty

7and must confess the sin they have committed. They must make full restitution for the wrong they have done, add a fifth of the value to it and give it all to the person they have wronged.

8But if that person has no close relative to whom restitution can be made for the wrong, the restitution belongs to the Lord and must be given to the priest, along with the ram with which atonement is made for the wrongdoer.
