2 Corinthians 3:14-16

14But the people’s minds were hardened, and to this day whenever the old covenant is being read, the same veil covers their minds so they cannot understand the truth. And this veil can be removed only by believing in Christ.

15Yes, even today when they read Moses’ writings, their hearts are covered with that veil, and they do not understand.

16But whenever someone turns to the Lord, the veil is taken away.
