The two tables of testimony - Compare Exodus 31:18.

The skin of his face shone - Compare Matthew 17:2. The brightness of the Eternal Glory, though Moses had witnessed it only in a modified manner Exodus 33:22-23, was so reflected in his face, that Aaron and the people were stricken with awe, and feared to approach him until he gave them words of encouragement.

The word translated "shine" is closely connected with a word translated "horn"; and hence, the Latin version and others have rendered the verb "to be horned." From this rendering of the word has arisen the popular representation of Moses with horns on his forehead; e. g. in Michaelangelo's statue at Rome.

The skin of his face shone - קרן karan, was horned: having been long in familiar intercourse with his Maker, his flesh, as well as his soul, was penetrated with the effulgence of the Divine glory, and his looks expressed the light and life which dwelt within. Probably Moses appeared now as he did when, in our Lord's transfiguration, he was seen with Elijah on the mount, Matthew 17. As the original word קרן karan signifies to shine out, to dart forth, as horns on the head of an animal, or rays of light reflected from a polished surface, we may suppose that the heavenly glory which filled the soul of this holy man darted out from his face in coruscations, in that manner in which light is generally represented. The Vulgate renders the passage, et ignorabat quod cornuta esset facies sua, "and he did not know that his face was horned;" which version, misunderstood, has induced painters in general to represent Moses with two very large horns, one proceeding from each temple. But we might naturally ask, while they were indulging themselves in such fancies, why only two horns? for it is very likely that there were hundreds of these radiations, proceeding at once from the face of Moses. It was no doubt from this very circumstance that almost all the nations of the world who have heard of this transaction, have agreed in representing those men to whom they attributed extraordinary sanctity, and whom they supposed to have had familiar intercourse with the Deity, with a lucid nimbus or glory round their heads. This has prevailed both in the east and in the west; not only the Greek and Roman saints, or eminent persons, are thus represented, but those also among the Mohammedans, Hindoos, and Chinese.

And it came to pass, when Moses came down Mount Sinai,.... Which was on the day of atonement, according to Jarchi, that is, the tenth of Tisri, or September; and so the Jewish chronologers (q) fix his descent on this day:

with the two tables of testimony in Moses's hand; the two tables he carried up, on which God had wrote the law, called "the testimony", being a testification and declaration of his will to the children of Israel:

when he came down from the mount, that Moses wist not that the skin of his face shone, while he talked with him: the Targum of Jonathan is,"Moses knew not that the splendour of the form of his face was become illustrious, which he had from the brightness of the glory of the Shechinah of the Lord, at the time he talked with him.''And this the apostle calls "the glory of his countenance", 2 Corinthians 3:7 the glory of the Lord as it passed before him, when in the cleft of the rock, and that degree of it he was admitted to the sight of, while conversing with God, during his stay on the mount forty days and forty nights, left a shining glory on his countenance; which while he was with God he could not be at all sensible of, the glory of God so infinitely surpassing that; and when he came down the mount, as he could not see his own face without a glass, so though the rays of light and glory that darted from his face were so bright and strong, that they might have been observed by him, yet his mind was so intent on what he had seen and heard, that he took no notice of them. The Vulgate Latin version renders it very wrongly, "that his face was horned", which has given occasion to painters to represent him in a ridiculous manner, as having horns coming out of his forehead; though the word has the signification of an horn, and the meaning of that version, as of others, may only be, that the skin of his face "darted out rays" (r) like horns, such as the rays of the sun appear to be like to the eye, see Habakkuk 3:4 hence Jupiter Ammon, the same with the sun, is described as having horns (s); and so Bacchus, who is supposed to be the same with Moses, is represented as having a horned face (t). Now this glory was left on the countenance of Moses, to show that he had had communion with God, and that the law he brought with him was from him; and to signify the glory of it, and to command awe and reverence, and make men afraid to break it.

The sight of the glory of Jehovah, though only of the back or reflection of it, produced such an effect upon Moses' face, that the skin of it shone, though without Moses observing it. When he came down from the mountain with the tables of the law in his hand, and the skin of his face shone אתּו בּדבּרו, i.e., on account of his talking with God, Aaron and the people were afraid to go near him when they saw the brightness of his face. But Moses called them to him, - Viz. first of all Aaron and the princes of the congregation to speak to them, and then all the people to give them the commandments of Jehovah; but on doing this (Exodus 34:33), he put a veil upon (before) his face, and only took it away when he went in before Jehovah to speak with Him, and then, when he came out (from the Lord out of the tabernacle, of course after the erection of the tabernacle), he made known His commands to the people. But while doing this, he put the veil upon his face again, and always wore it in his ordinary intercourse with the people (Exodus 34:34, Exodus 34:35). This reflection of the splendour thrown back by the glory of God was henceforth to serve as the most striking proof of the confidential relation in which Moses stood to Jehovah, and to set forth the glory of the office which Moses filled. The Apostle Paul embraces this view in 2 Corinthians 3:7., and lays stress upon the fact that the glory was to be done away, which he was quite justified in doing, although nothing is said in the Old Testament about the glory being transient, from the simple fact that Moses died. The apostle refers to it for the purpose of contrasting the perishable glory of the law with the far higher and imperishable glory of the Gospel. At the same time he regards the veil which covered Moses' face as a symbol of the obscuring of the truth revealed in the Old Testament. But this does not exhaust the significance of this splendour. The office could only confer such glory upon the possessor by virtue of the glory of the blessings which it contained, and conveyed to those for whom it was established. Consequently, the brilliant light on Moses' face also set forth the glory of the Old Covenant, and was intended both for Moses and the people as a foresight and pledge of the glory to which Jehovah had called, and would eventually exalt, the people of His possession.

And it came to pass, when Moses came down from mount Sinai with the two tables of testimony in Moses' hand, when he came down from the mount, that Moses wist not that the skin of his face shone while he talked with him.

34:29 The skin of his face shone - This time of his being in the mount he heard only the same he had heard before. But he saw more of the glory of God, which having with open face beheld, he was in some measure changed into the same image. This was a great honour done to Moses, that the people might never again question his mission, or think or speak slightly of him. He carried his credentials in his very countenance, some think as long as he lived, he retained some remainders of this glory, which perhaps contributed to the vigour of his old age; that eye could not wax dim which had seen God, nor that face wrinkle which had shone with his glory.

29. Moses wist not that the skin of his face shone while he talked with him-It was an intimation of the exalted presence into which he had been admitted and of the glory he had witnessed (2Co 3:18); and in that view, it was a badge of his high office as the ambassador of God. No testimonial needed to be produced. He bore his credentials on his very face; and whether this extraordinary effulgence was a permanent or merely temporary distinction, it cannot be doubted that this reflected glory was given him as an honor before all the people.

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.
