Deuteronomy 19:5-7

Contemporary English Version

⁵ For example, suppose you and a friend go into the forest to cut wood. You are chopping down a tree with an ax, when the ax head slips off the handle, hits your friend, and kills him. You can run to one of the Safe Towns and save your life. ⁶ You don't deserve to die, since you did not mean to harm your friend. But he did get killed, and his relatives might be very angry. They might even choose one of the men from their family to track you down and kill you. If it is too far to one of the Safe Towns, the victim's relative might be able to catch you and kill you. ⁷ That's why I said there must be three Safe Towns.
