Matthew Poole and continuators on 1 Corinthians 14:19

19 Yet in the church I had rather speak five words with my understanding, that by my voice I might teach others also, then ten thousand words in an unknown tongue .

Yet he had so great a regard to the end of his Ministry, teaching others, and communicating Divine knowledge to them, that he had rather speak a little tending to that end, than never so much in a Language, which those to whom he spake, did not understand.
