2 Corinthians 3:13-16

and are not like Moses, who used to put a veil over his face so that the sons of Israel would not look intently at the end of what was fading away. But their minds were hardened; for until this very day at the reading of the old covenant the same veil remains unlifted, because it is removed in Christ. But to this day whenever Moses is read, a veil lies over their heart; but whenever a person turns to the Lord, the veil is taken away.
