English: “He is a murderer” — what does this teach? To tell you: for his [own] murder you put him to death, but you do not put him to death for the killing done by his ox.
Distinction between personal homicide and liability for an animal’s act.
Capital execution applies only to the person’s own murderous act, not to a death caused by his ox (which has a separate civil/tort regime).
