2 Corinthians 11:6 - Coke's Commentary on the Holy Bible

Rude in speech,— The word ιδιωτης, rendered rude, frequently signifies a private man; one who can speak no better than the generality of his neighbours, being unformed by the rules of eloquence. But whether this sense be applicable to St. Paul, let those judge, who are able to compare his stile with the best Classic writers among the Greeks: let them likewise judge, who are warmed with the pathos and sublimity of his sentiments. To say that this could be his meaning, would, on such a comparison, appear highly absurd; but to apply it to a natural impediment in his speech, is consistent both with the pathos, the sublimity, and correctness of his stile; and is the only sense, I believe, in which it can be understood with the least degree of propriety.
