Numbers 35:18

And if he should strike him with an instrument of wood from his hand, whereby he may die, and he [thus] die, he is a murderer; let the murderer by all means 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.

Or if he struck him with a weapon of wood in the hand, by which a man may die, and he died, he is a murderer. The murderer shall surely be put to death.
