1. A holy assembly (1-14)
The Law strictly regulated who could be a part of the assembly of God's people. God remembers the past record and holds a people responsible for the sins of their fathers. But the God of grace welcomes all people who have faith. (Think about the women in Jesus' genealogy--all are exceptions to these rules--Mt 1.) The Lord moves about in the camp to protect his people, so the camp must be kept clean and decent.
2. Special rules for a holy people (15-25)
God does not want his people to oppress others; he does not want them to be involved in the immoral orgies of the Canaanite religions. He wants them to be responsible for what they say and generous with what they have.
Application: Lord, thank you for your grace. Thank you for the precious blood of Jesus that redeems me from the empty way of life handed down from my forefathers. Help me to keep my heart and life pure, and be generous with others.
One Word: The Lord is in the camp.
