Deuteronomy 19:3-5

New Life Version

³ Make the roads good that lead to these cities. Divide into three parts the land the Lord your God gives you for your own. Any man who kills another may run to a city and be safe.

⁴ “This is the law of the person who kills another and runs to a city to save his life. He might have killed his friend without meaning to, a friend he did not hate in the past. ⁵ He could have gone among the trees with his friend to cut wood. As he was using his ax to cut down a tree, the ax head could have come off the stick and hit his friend, killing him. Then he may run to one of these cities and live.
