29 And it cometh to pass, when Moses is coming down from mount Sinai (and the two tables of the testimony 'are' in the hand of Moses in his coming down from the mount), that Moses hath not known that the skin of his face hath shone in His speaking with him, 30 and Aaron seeth—all the sons of Israel also—Moses, and lo, the skin of his face hath shone, and they are afraid of coming nigh unto him. 31 And Moses calleth unto them, and Aaron and all the princes in the company return unto him, and Moses speaketh unto them; 32 and afterwards have all the sons of Israel come nigh, and he chargeth them with all that Jehovah hath spoken with him in mount Sinai. 33 And Moses finisheth speaking with them, and putteth on his face a vail; 34 and in the going in of Moses before Jehovah to speak with Him, he turneth aside the vail until his coming out; and he hath come out and hath spoken unto the sons of Israel that which he is commanded; 35 and the sons of Israel have seen the face of Moses that the skin of the face of Moses hath shone, and Moses hath put back the vail on his face until his going in to speak with Him.

Commentary on Exodus 34:28-35

(Read Exodus 34:28-35)

Near and spiritual communion with God improves the graces of a renewed and holy character. Serious godliness puts a lustre upon a man's countenance, such as commands esteem and affection. The vail which Moses put on, marked the obscurity of that dispensation, compared with the gospel dispensation of the New Testament. It was also an emblem of the natural vail on the hearts of men respecting spiritual things. Also the vail that was and is upon the nation of Israel, which can only be taken away by the Spirit of the Lord showing to them Christ, as the end of the law for righteousness to every one that believeth. Fear and unbelief would put the vail before us, they would hinder our free approach to the mercy-seat above. We should spread our wants, temporal and spiritual, fully before our heavenly Father; we should tell him our hinderances, struggles, trails, and temptations; we should acknowledge our offences.
