Numbers 35:25-27

Revised Standard Version

²⁵ and the congregation shall rescue the manslayer from the hand of the avenger of blood, and the congregation shall restore him to his city of refuge, to which he had fled, and he shall live in it until the death of the high priest who was anointed with the holy oil. ²⁶ But if the manslayer shall at any time go beyond the bounds of his city of refuge to which he fled, ²⁷ and the avenger of blood finds him outside the bounds of his city of refuge, and the avenger of blood slays the manslayer, he shall not be guilty of blood.
