2 Corinthians 3:7, 11, 14

The old way, with laws etched in stone, led to death, though it began with such glory that the people of Israel could not bear to look at Moses’ face. For his face shone with the glory of God, even though the brightness was already fading away.

So if the old way, which has been replaced, was glorious, how much more glorious is the new, which remains forever!

But 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.
