Numbers 35:26-28

New Catholic Bible

²⁶ “ ‘But if the killer at any time crosses over the boundary of the city of refuge to which he has fled, ²⁷ and the kinsman avenger of blood finds him outside of the boundary of the city of refuge, and the kinsman avenger of blood kills the killer, he will not be considered to have blood guilt. ²⁸ He should have remained in the city of refuge until the death of the high priest. After the death of the high priest, the killer can return to the land of his possession.
