1 Corinthians 14:11

If then. know not the meaning of the voice,. shall be to him that speaketh. barbarian, and he that speaketh will be. barbarian unto me.

'I know not the meaning of the voice' -i.e. the meaning of the language being spoken.. situation identical to what was occuring with the abuse of tongues in the Corinthian congregation.

'barbarian' -'a favorite racial slur cast by Greeks on non-Greek speaking people.' (McGuiggan p. 181) 'For all ignorant of Greek language and culture.' (Robertson p. 182)

'Where's the advantage to being able to speak all of the languages of the world if the people you are speaking to don't understand them?...Does the tongue-speaker think people will think him wonderful because he can speak all these languages? If people are bombarded with language they don't understand (especially when they're looking for edification) they'll think the speaker is. barbarian..Not only will that create poor relations between the hearer and the speaker, it will work back the other way. The speaker will look down on those who can't appreciate what he is doing..The pride-filled tongue-speaker can't understand why these "peons" don't appreciate him and the listeners can't abide his parading (what to them is) his babbling.' (McGuiggan p. 181)
