Numbers 35:14

¹²And the cities shall be to you places of refuge from the avenger of blood, and the slayer shall not die until he stands before the congregation for judgment.

¹³And the cities which ye shall assign, even the six cities, shall be places of refuge for you.

— Numbers 35:14 —

¹⁵It shall be a place of refuge for the children of Israel, and for the stranger, and for him that sojourns among you; these cities shall be for a place of refuge, for every one to flee thither who has killed a man unintentionally.

¹⁶And if he should smite him with an iron instrument, and the man should die, he is a murderer; let the murderer by all means be put to death.
