Numbers 35:16
King James Version (1769 Blayney revision, with Apocrypha) · Berean Standard Bible
And if he smite him with an instrument of iron, so that he die, he is a murderer: the murderer shall surely be put to death.
If, however, anyone strikes a person with an iron object and kills him, he is a murderer; the murderer must surely be put to death.
