2 Corinthians 3:13-16

13and we are not like Moses, who used to put a veil over his face so that the Israelites would not gaze at the end of the glory which was fading away.

14But [in fact] their minds were hardened [for they had lost the ability to understand]; for until this very day at the reading of the old covenant the same veil remains unlifted, because it is removed [only] in Christ.

15But to this day whenever Moses is read, a veil [of blindness] lies over their heart;

16but whenever a person turns [in repentance and faith] to the Lord, the veil is taken away.
