Numbers 35:26-28

Evangelical Heritage Version

²⁶ But if the person who has killed someone ever goes outside of the border of the city of refuge to which he has fled, ²⁷ and the avenger of blood finds him outside of the border of his city of refuge, and the avenger of blood kills the person who has killed someone, the avenger will not be guilty of bloodshed, ²⁸ because the person who has killed someone should have stayed in his city of refuge until the death of the high priest. But after the death of the high priest he may return to the land that is his possession.
