Numbers 35:26-28

Modern English Version

²⁶ But if the manslayer will go out at any time beyond the border of the city of his refuge where he fled, ²⁷ and the avenger of blood finds him outside the borders of the city of his refuge, and the avenger of blood kills the manslayer, he will not be guilty of blood, ²⁸ because the manslayer should have remained in the city of his refuge until the death of the high priest. But after the death of the high priest the manslayer may return to the land of his possession.
