But if the ministration of death, written and engraven in stones, was glorious, so that the children of Israel could not stedfastly behold the face of Moses for the glory of his countenance; which glory was to be done away: The ministration of death - Here the apostle evidently intends the law. It was a ministration, διακονια or service of death. It was the province of the law to ascertain the duty of man; to assign his duties; to fix penalties for transgressions, etc.; and by it is the knowledge of sin. As man is prone to sin, and is continually committing it, this law was to him a continual ministration of death. Its letter killed; and it was only the Gospel to which it referred that could give life, because that Gospel held out the only available atonement.
Yet this ministration of death (the ten commandments, written on stones; a part of the Mosaic institutions being put for the whole) was glorious - was full of splendor; for the apostle refers to the thunderings, and lightnings, and luminous appearances, which took place in the giving of the law; so that the very body of Moses partook of the effulgence in such a manner that the children of Israel could not look upon his face; and he, to hide it, was obliged to use a veil. All this was intended to show the excellency of that law, as an institution coming immediately from God: and the apostle gives it all its heightenings, that he may compare it to the Gospel, and thereby prove that, glorious as it was, it had no glory that could be compared with that of the Gospel; and that even the glory it had was a glory that was to be done away - to be absorbed, as the light of the stars, planets, and moon, is absorbed in the splendor of the sun. See the notes on Romans 7 (note); and see those on Exodus 19 (note), Exodus 20 (note), and Exodus 34:29 (note), etc., where this subject is treated in all its details.
