1. God established the cities of refuge (1-6)
God was concerned about upholding justice. If a person killed someone by accident, then they could flee to the city of refuge and live there, protected from any who would seek to kill them. They would stand trial and, if innocent, after the death of the high priest, they could return to their town. God understands our tendency to seek revenge. He makes a way for people to be saved from injustice.
2. God wants equal access to this refuge (7-9)
Six cities of refuge were evenly distributed throughout the land. People from every tribe would have equal access to refuge. No one tribe would have an advantage. God is a refuge for those suffering from injustice. In a world that is full of revenge, God's mercy and grace shines forth.
