Exodus 21:14
But if a man schemes and acts willfully against his neighbor to kill him, you must take him away from My altar to be put to death.
Numbers 35:16–21
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. / Or if anyone has in his hand a stone of deadly size, and he strikes and kills another, he is a murderer; the murderer must surely be put to death. / If anyone has in his hand a deadly object of wood, and he strikes and kills another, he is a murderer; the murderer must surely be put to death.
