American Tract Society Bible Dictionary
According to the Greek idiom, all other nations, however learned and polite they might be, were "barbarians." Hence Paul comprehends all mankind under the names of "Greeks and barbarians," Romans 1:14 . Luke calls the inhabitants of the island of Malta, "barbarians," Acts 28:2,4 . Indeed, "barbarian" is used in Scripture for every stranger or foreigner who does not speak the native language of the writer, Psalm 114:1 , and includes no implication whatever of savage nature or manners in those respecting whom it is used.
