Deuteronomy 5:17-18

5:17 You must not murder. ¹  5:18 You must not commit adultery.

[5:17]  ¹ 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.”
