But even unto this day - To the time when Paul wrote this Epistle, about 30 years after Christ was put to death. But it is still as true as it was in the time of Paul; and the character and conduct of the Jews now so entirely accords with the description which he gives of them in his time, as to show that he drew from nature, and as to constitute one of the strong incidental proofs that the account in the New Testament is true. Of no other people on earth, probably, would a description be accurate eighteen hundred years after it was made.
When Moses is read - When the five books of Moses are read, as they were regularly and constantly in their synagogues; see the note on Luke 4:16.
The vail is upon their heart - They do not see the true meaning and beauty of their own Scriptures - a description as applicable to the Jews now as it was to those in the time of Paul.

But even unto this day, when Moses is read,.... These words are an explanation of the former, and show that by the Old Testament is designed, more especially, Moses, or the writings of Moses; which were frequently read, and preached upon in the Jewish synagogues; see Acts 13:15 and that by "the veil untaken away", is meant,
the veil upon their heart; that is, the veil of blindness, ignorance of Christ, and the Gospel; of the prophecies of the Old Testament, and even of the law itself, its nature, use, and end; preferring the traditions of their fathers, before the written law of Moses.

the veil is--rather, "a veil lieth upon their heart" (their understanding, affected by the corrupt will, John 8:43; 1-Corinthians 2:14). The Tallith was worn in the synagogue by every worshipper, and to this veil hanging over the breast there may be an indirect allusion here (see on 1-Corinthians 11:4): the apostle making it symbolize the spiritual veil on their heart.
