And the cities shall be to flee from the executer of blood, that he which killed die not, until he stand before the congregation in judgment.

then the congregation shall judge between the slayer and the executer of blood in such cases.

Lest the executer of blood follow after the slayer while his heart is hot and overtake him, because the way is long, and slay him, and yet there is no cause worthy of death in him, inasmuch as he hated not his neighbour in time past.
