[20:13] 1 tn The verb רָצַח (ratsakh) refers to the premeditated or accidental taking of the life of another human being; it includes any unauthorized killing (it is used for the punishment of a murderer, but that would not be included in the prohibition). This commandment teaches the sanctity of all human life. See J. H. Yoder, “Exodus 20,13: ‘Thou Shalt Not Kill’,” Int 34 (1980): 394-99; and A. Phillips, “Another Look at Murder,” JJS 28 (1977): 105-26.
[5:17] 2 tn Traditionally “kill” (so KJV, ASV, RSV, NAB). The verb here (רָצַח, ratsakh) is generic for homicide but in the OT both killing in war and capital punishment were permitted and even commanded (Deut 13:5, 9; 20:13, 16-17), so the technical meaning here is “murder.”
