Numbers 35:26-28

English Standard Version

²⁶ But if the manslayer shall at any time go beyond the boundaries of his city of refuge to which he fled, ²⁷ and ^(A)the avenger of blood finds him outside the boundaries of his city of refuge, and the avenger of blood kills the manslayer, he shall not be guilty of blood. ²⁸ For he must remain in his city of refuge ^(B)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.
