2 Corinthians 3:14-17

but their minds were hardened: for until this very day at the reading of the old covenant the same veil remaineth, it not being revealed to them that it is done away in Christ. But unto this day, whensoever Moses is read, a veil lieth upon their heart. But whensoever it shall turn to the Lord, the veil is taken away. Now the Lord is the Spirit: and where the Spirit of the Lord is, there is liberty.
