*20:3 Lit without knowledge. The Hebrew terminology is not very precise, but adequate nonetheless to distinguish involuntary manslaughter from murder. In modern terms, the person who is guilty only of manslaughter must not have been aware at the time that he was actually killing a human being (like the hunter who mistakes a man for an animal of prey); or if he knew that his actions were affecting another human, he must not have been aware that those actions could result in the death of the other person. In v 5, it is also stated that the perpetrator must not have had hatred for the victim, and it is implied that if hatred was a factor, the killer is automatically ruled a murderer (cf Num 35:20, 21).
†20:3 Lit redeemer of blood, the idea being that the one who kills the murderer of a relative redeems the guilt of the crime. The avenger was ordinarily a male next-of-kin, and he had the right, or even the responsibility, to execute the guilty party.
‡20:4 Lit speak his word in the hearing of.
§20:5 Lit without knowledge.
*20:6 If judged guilty, the killer would be put to death. Otherwise, the time he was required to spend in the city of refuge represented a less severe punishment for involuntary manslaughter. Afterward, he was entitled to return home and live in safety. If the blood avenger killed him then, the avenger would be guilty of murder.
