Numbers 35:15-17

Darby Translation

¹⁵ For the children of Israel, and for the stranger, and for the sojourner among them shall these six cities be a refuge, that one who smiteth a person mortally without intent may flee thither.

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

¹⁷ And if he have smitten him with a stone from the hand, wherewith one may die, and he die, he is a murderer: the murderer shall certainly be put to death.
