3:12-18 It is the duty of the ministers of the gospel to use great plainness, or clearness, of speech. The Old Testament believers had only cloudy and passing glimpses of that glorious Saviour, and unbelievers looked no further than to the outward institution. But the great precepts of the gospel, believe, love, obey, are truths stated as clearly as possible. And the whole doctrine of Christ crucified, is made as plain as human language can make it. Those who lived under the law, had a veil upon their hearts. This veil is taken away by the doctrines of the Bible about Christ. When any person is converted to God, then the veil of ignorance is taken away. The condition of those who enjoy and believe the gospel is happy, for the heart is set at liberty to run the ways of God's commandments. They have light, and with open face they behold the glory of the Lord. Christians should prize and improve these privileges. We should not rest contented without knowing the transforming power of the gospel, by the working of the Spirit, bringing us to seek to be like the temper and tendency of the glorious gospel of our Lord and Saviour Jesus Christ, and into union with Him. We behold Christ, as in the glass of his word; and as the reflection from a mirror causes the face to shine, the faces of Christians shine also.
13. We use no disguise, "as Moses put a veil over his face, that the children of Israel might not look steadfastly upon the end of that which was to be done away" [Ellicott and others]. The view of Ex 34:30-35, according to the Septuagint is adopted by Paul, that Moses in going in to speak to God removed the veil till he came out and had spoken to the people; and then when he had done speaking, he put on the veil that they might not look on the end, or the fading, of that transitory glory. The veil was the symbol of concealment, put on directly after Moses' speaking; so that God's revelations by him were interrupted by intervals of concealment [ALFORD]. But Alford's view does not accord with 2Co 3:7; the Israelites "could not look steadfastly on the face of Moses for the glory of his countenance." Plainly Moses' veil was put on because of their not having been able to "look steadfastly at him." Paul here (2Co 3:13) passes from the literal fact to the truth symbolized by it, the blindness of Jews and Judaizers to the ultimate end of the law: stating that Moses put on the veil that they might not look steadfastly at (Christ, Ro 10:4) the end of that (law) which (like Moses' glory) is done away. Not that Moses had this purpose; but often God attributes to His prophets the purpose which He has Himself. Because the Jews would not see, God judicially gave them up so as not to see. The glory of Moses' face is antitypically Christ s glory shining behind the veil of legal ordinances. The veil which has been taken off to the believer is left on to the unbelieving Jew, so that he should not see (Isa 6:10; Ac 28:26, 27). He stops short at the letter of the law, not seeing the end of it. The evangelical glory of the law, like the shining of Moses' face, cannot be borne by a carnal people, and therefore remains veiled to them until the Spirit comes to take away the veil (2Co 3:14-17) [Cameron].
