I suppose the Jews and a few million others would have been wrong in Paul’s eyes to have rebelled against Hitler and the murderous Nazis because God placed them in authority? NOT buying it.
Similarly the commandment thou shalt not KILL-which some scholars believe(and as most people have always acted) was originally thou shalt not MURDER;else we would be constrained from defending ourselves and our loved ones.Plus the Israelites killed quite a few in gaining the Promised Land.
Back when the King James bible was Authorized Kill and Murder were essentially synonyms, and this remains even today as one of the definitions of Kill is "to murder" and seen in phrases like "there's a killer on the loose!" (if it were someone who merely ended some life like, say, a hunter that sort of warning would be seen as inappropriate).
