Numbers 5:1-31
5:1-4 Moses is instructed by God to separate the people with contagious illnesses from the rest. This is not a punishment but a health precaution for the healthy.
5:5-10 God teaches Moses that a person who is guilty and seeking forgiveness must right their wrong. They must offer back what they took from their victim, plus 1/5 more. If the victim is unable to receive the restitution (the restoration of what they had), the culprit should make the donation to the church.
5:11-31 Unfaithful spouses were encouraged to settle their disputes in front of the eyes of God. Their methods are a bit antiquated but essentially the process was to have the person confess the truth before God.
