II Corinthians 3:13-16

unlike Moses, who put a veil over his face so that the children of Israel could not look steadily at the end of what was passing away. But their minds were blinded. For until this day the same veil remains unlifted in the reading of the Old Testament, because the veil is taken away in Christ. But even to this day, when Moses is read, a veil lies on their heart. Nevertheless when one turns to the Lord, the veil is taken away.
