V. 15.— Whereof the Holy Ghost also is a witness to us; for after that he had said before. The Apostle here confirms what he had said by the testimony of the Holy Ghost. This language merits our particular attention. It demonstrates the verbal inspiration of the Scriptures. The Apostles spoke not in the word which man’ s wisdom taught, but that which the Holy Ghost taught. He then proceeds to quote the words of the Holy Ghost which he had mentioned before.
