Numbers 35:25-27

NSB(i) 25 »If you are innocent, the community must protect you from that relative. They must take you back to the city of refuge you fled to. You must live there until the death of the chief priest who was anointed with the holy oil. 26 »But do not go outside the city of refuge you fled to. 27 »If the relative who can avenge the death finds you outside the city of refuge and kills you, the relative is not guilty of murder.
