‘The cities you give the Levites will include six cities of refuge, which you will provide so that the one who kills someone may flee there; in addition to these, give forty-two other cities.
Someone could flee there who committed manslaughter, killing his neighbour accidentally without previously hating him. He could flee to one of these cities and stay alive:
These six cities will serve as a refuge for the Israelites and for the foreigner or temporary resident among them, so that anyone who kills a person unintentionally may flee there.
