2 Corinthians 3:11 (KJV)

Who also hath made us able ministers of the new testament; not of the letter, but of the spirit: for the letter killeth, but the spirit giveth life.

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:

How shall not the ministration of the spirit be rather glorious?

For if the ministration of condemnation be glory, much more doth the ministration of righteousness exceed in glory.

For even that which was made glorious had no glory in this respect, by reason of the glory that excelleth.

Seeing then that we have such hope, we use great plainness of speech:

And not as Moses, which put a vail over his face, that the children of Israel could not stedfastly look to the end of that which is abolished:

But their minds were blinded: for until this day remaineth the same vail untaken away in the reading of the old testament; which vail is done away in Christ.

But even unto this day, when Moses is read, the vail is upon their heart.

Nevertheless when it shall turn to the Lord, the vail shall be taken away.
