2 Corinthians 3:7-18 NRSV
Now if the ministry of death, chiseled in letters on stone tablets, came in glory so that the people of Israel could not gaze at Moses' face because of the glory of his face, a glory now set aside, how much more will the ministry of the Spirit come in glory? For if there was glory in the ministry of condemnation, much more does the ministry of justification abound in glory! Indeed, what once had glory has lost its glory because of the greater glory; for if what was set aside came through glory, much more has the permanent come in glory!
Since, then, we have such a hope, we act with great boldness, not like Moses, who put a veil over his face to keep the people of Israel from gazing at the end of the glory that was being set aside. But their minds were hardened. Indeed, to this very day, when they hear the reading of the old covenant, that same veil is still there, since only in Christ is it set aside. Indeed, to this very day whenever Moses is read, a veil lies over their minds; but when one turns to the Lord, the veil is removed. Now the Lord is the Spirit, and where the Spirit of the Lord is, there is freedom. And all of us, with unveiled faces, seeing the glory of the Lord as though reflected in a mirror, are being transformed into the same image from one degree of glory to another; for this comes from the Lord, the Spirit.
