Joshua 20:3

Wycliffe Bible

³ that whoever slayeth unwittingly a man, flee to those cities; that when he hath fled to one of those cities, he may escape the ire of the neighbour, which is venger of blood. (so that whoever unwittingly killeth someone, can flee to those cities; so that when he hath fled to one of these cities, he can escape the anger of the neighbour, who avengeth the blood.)
