These were the appointed cities for all the children of Israel, and for the
alien who lives among them, that whoever kills any person unintentionally might flee there, and not die by the hand of the avenger of blood, until he stands trial before the congregation.
Jos 20:1-6. THE LORD COMMANDS THE CITIES OF REFUGE.
1-3. The Lord spake unto Joshua . . . Appoint out for you cities of refuge--(See Nu 35:9-28; De 19:1-13). The command here recorded was given on their going to occupy their allotted settlements. The sanctuaries were not temples or altars, as in other countries, but inhabited cities; and the design was not to screen criminals, but only to afford the homicide protection from the vengeance of the deceased's relatives until it should have been ascertained whether the death had resulted from accident and momentary passion, or from premeditated malice. The institution of the cities of refuge, together with the rules prescribed for the guidance of those who sought an asylum within their walls, was an important provision, tending to secure the ends of justice as well as of mercy.
