Numbers 35:27-29

Amplified Bible, Classic Edition

²⁷ And the avenger of blood finds him outside the limits of his city of refuge and kills the manslayer, he shall not be guilty of blood

²⁸ Because the manslayer should have remained in his city of refuge until the death of the high priest. But after the high priest’s death the manslayer shall return to the land of his possession.

²⁹ And these things shall be for a statute and ordinance to you throughout your generations in all your dwellings.
