Restitution for Wrongs

Numbers 5:1-10
Command the Israelites to send away from the camp anyone who has a defiling skin disease or a discharge of any kind, or who is ceremonially unclean because of a dead body. Send away male and female alike; send them outside the camp so they will not defile their camp, where I dwell among them.
Restitution歸還 for Wrongs
Any man or woman who wrongs another in any way and so is unfaithful to the Lord is guilty  and 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.
But 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.
V1-4: those who ate 'unclean' are sent into quarantine隔離.
V5-10: provide for compensation when one person wrongs another.
Why?
For God is Holy, so anyone comes to Him, have to be clean. Even skin disease or has sin against the Lord.
God is righteousness so his people have to do right things. Any wrong doer have to make compensation full restitution and add fifth of the value.
Priset is the servant of the Lord, so they may received the ram from wrong doers.
How?
God is holy so fear the Lord and do the right things. Restitution is need for wrongs.
