Matthew Poole and continuators on 1 Corinthians 14:11

11 Therefore if I know not the meaning of the voice, I shall be to him that speaketh a barbarian, and he that speaketh shall be a barbarian unto me .

But if a man doth not understand the Language, the words are not significant unto him, I shall neither understand him, nor will he understand me; for a Barbarian cannot understand one of another Nation, till he hath learned the Language of that Nation▪ nor can a man of another Nation understand a Barbarian, till he hath learned his Language.
