Numbers 35:14

¹²And they shall be unto you cities for refuge from the avenger; that the manslayer die not, until he stand before the congregation in judgment.

¹³And of these cities which ye shall give six cities shall ye have for refuge.

— Numbers 35:14 —

¹⁵These six cities shall be a refuge, both for the children of Israel, and for the stranger, and for the sojourner among them: that every one that killeth any person unawares may flee thither.

¹⁶And if he smite him with an instrument of iron, so that he die, he is a murderer: the murderer shall surely be put to death.
