Numbers 35:17

And if he struck him down with a stone tool that could cause death , and he died , he is a murderer . The murderer shall be put to death .

Or if anyone is holding a stone and strikes someone a fatal blow with it, that person is a murderer; the murderer is to be put to death.

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.
