1. Because the Holy God dwells among you (1-10)

God wanted his people to be pure in body and in heart. So the camp must be kept clean, and hearts defiled by sin must be purified. Sin must be confessed, restitution made to the person who was injured, and a blood sacrifice offered to God for atonement. A man who wrongs another and does not set it right is unfaithful to the Lord.

2. The law of jealousy (11-15;29-31)

A person who is unfaithful to his or her marriage vows is defiled. A jealous heart also defiles a person, for jealousy makes it impossible for one to see himself and others from God's point of view. The Law of jealousy was given to remove jealousy from a person's heart. If there is a legitimate reason for jealousy, then the person who has been unfaithful must be punished. If there is no reason for being jealous, then the jealous person must repent and cast jealousy out of his or her heart.

Application: Lord, purify my heart. Remove all jealousy and anger and bitterness from my heart, so that you may dwell with me.
One Word: A holy God; a pure heart
