Numbers 35:15-17

King James Version

¹⁵ These 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.

¹⁶ And 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.

¹⁷ And if he smite him with throwing a stone, wherewith he may die, and he die, he is a murderer: the murderer shall surely be put to death.
