Numbers 35:18

Or if he struck him down with a wooden 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 wooden object and strikes someone a fatal blow with it, that person is a murderer; the murderer is to be put to death.

Or if he smite him with an hand weapon of wood, wherewith he may die, and he die, he is a murderer : the murderer shall surely be put to death.
