Numbers 35:27-29

Lexham English Bible

²⁷ and the blood avenger finds him outside the territory of the city of his refuge, and the blood avenger kills the killer, he will not be guilty of blood^{[a] 28} because he must live in the city of his refuge until the death of the high priest. But after the death of the high priest the killer will return to the land of his property. ²⁹ These things will be as a decree of justice for you for your generations in all your dwellings.
