Numbers 35

22 Ref But if he thrust him suddenly without enmity, or hurled on him anything without lying in wait,
23 or with any stone, by which a man may die, not seeing him, and cast it on him, so that he died, and he was not his enemy, neither sought his harm;
24 Ref then the congregation shall judge between the striker and the avenger of blood according to these ordinances;

26 But if the manslayer shall at any time go beyond the border of his city of refuge, where he flees,
27 Ref 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,
