I. God appeared in his glory, so as he never did before or since (v. 3, 4): He came from Teman, even the Holy One from Mount Paran. This refers to the visible display of the glory of God when he gave the law upon Mount Sinai, as appears by Deut. xxxiii. 2 whence these expressions are borrowed. Then the Lord came down upon Mount Sinai in a cloud (Exod. xix. 20) and his glory was as the devouring fire, not only to enforce the law he then gave them, but to avow the deliverance he had wrought for them and to magnify it; for the first word he said there was, "I am the Lord thy God, that brought thee out of the land of Egypt. I that appear in this glory am the author of that work." Then his glory covered the heavens, which shone with the reflection of that glorious appearance of his; the earth also was full of his praise, or of his splendour, as some read it. People at a distance saw the cloud and fire on the top of Mount Sinai, and praised the God of Israel. Or the earth was full of those works of God which were to be praised. His brightness was as the light, as the light of the sun when he goes forth in his strength; he had horns, or bright beams (so it should be rendered), coming out of his side or hand. Rays of glory were darted forth around him; and with some rays borrowed thence it was that Moses's face shone when he came down from that mount of glory. Some by the horns, the two horns (for the word is dual), coming out of his hand, understand the two tables of the law, which perhaps, when God delivered them to Moses, though they were tables of stone, had a glory round them; those books were gilt with beams, and so it agrees with Deut. xxxiii. 2, From his right hand went a fiery law for them. It is added, And there was the hiding of his power; there was his hidden power, in the rays that came out of his hand. The operations of his power, compared with what he could have done, were rather the hiding of it than the discovery of it; the secrets of his power, as well as of his wisdom, are double to that which is, Job xi. 6.
