2 Corinthians 3:12-16 12Seeing then that we have such hope, we use great plainness of speech: 13And not as Moses, which put a vail over his face, that the children of Israel could not stedfastly look to the end of that which is abolished: 14But their minds were blinded: for until this day remaineth the same vail untaken away in the reading of the old testament; which vail is done away in Christ. 15But even unto this day, when Moses is read, the vail is upon their heart. 16Nevertheless when it shall turn to the Lord, the vail shall be taken away. (2 Cor. 3:12-16 KJV)

The Apostle Paul quotes Exodus 34:34 to give the analogy of one who turns the Jesus will find salvation – 34But when Moses went in before the LORD to speak with him, he took the vail off, until he came out. And he came out, and spake unto the children of Israel that which he was commanded. (Exod. 34:34 KJV)
