Numbers 35:26 WEB

²⁴  then the congregation shall judge between the striker and the avenger of blood according to these ordinances;

²⁵  and the congregation shall deliver the manslayer out of the hand of the avenger of blood, and the congregation shall restore him to his city of refuge, where he was fled: and he shall dwell therein 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 border of his city of refuge, where he flees,

²⁷  and the avenger of blood find him outside of the border of his city of refuge, and the avenger of blood kill the manslayer; he shall not be guilty of blood,

²⁸  because he should have remained in his city of refuge until the death of the high priest: but after the death of the high priest the manslayer shall return into the land of his possession.
