John 9:32

Verse 32. Since the world began. Neither Moses nor any of the prophets had ever done this. No instance of this kind is recorded in the Old Testament. As this was a miracle which had never been performed, the man argued justly that he who had done it must be from God. As Jesus did it not by surgical operations, but by clay, it showed that he had power of working miracles by any means. It may be also remarked that the restoration of sight to the blind by surgical operations was never performed until the year 1728. Dr. Cheselden, an English surgeon, was the first who attempted it successfully, who was enabled to remove a cataract from the eye of a young man, and to restore sight.
