1 Corinthians 14:11

11But if I do not know the meaning of the language, I will [appear to] be a 14:11 Lit barbarian, i.e. one who did not speak Greek; especially a person from an uncivilized region whose speech could not be readily translated.foreigner to the one who is speaking [since he knows exactly what he is saying], and the one who is speaking will [appear to] be a foreigner to me.
