Numbers 35:17 ASV

¹⁵  For the children of Israel, and for the stranger and for the sojourner among them, shall these six cities be for refuge; that every one that killeth any person unwittingly may flee thither.

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

¹⁷  And if he smote him with a stone in the hand, whereby a man may die, and he died, he is a murderer: the murderer shall surely be put to death.

¹⁸  Or if he smote him with a weapon of wood in the hand, whereby a man may die, and he died, he is a murderer: the murderer shall surely be put to death.

¹⁹  The avenger of blood shall himself put the murderer to death: when he meeteth him, he shall put him to death.
