They were afraid to come nigh him - A sight of his face alarmed them; their consciences were still guilty from their late transgression, and they had not yet received the atonement. The very appearance of superior sanctity often awes the guilty into respect.

And when Aaron and all the children of Israel saw Moses,.... Who very probably met him at the bottom of the mount; these Israelites with Aaron were the princes, as Aben Ezra seems rightly to interpret it, and as appears from the following verse; for Moses could not well be seen by the whole body of the people at once, upon his descent from the mount:

behold, the skin of his face shone; darted out rays of light and glory all around it, much perhaps in the same manner as the glory about our Lord, and others, is painted by the Romanists:

and they were afraid to come nigh him; there was something so majestic and striking in it; and perhaps they could not tell whether it foreboded good or evil to them; and this may signify, that as by the light of the law sin is discovered, it fills with a sense of wrath and fear of damnation; and being the ministration of condemnation and death, it is terrifying and killing, though it has a glory in it.

And when Aaron and all the children of Israel saw Moses, behold, the skin of his face shone; and they were afraid to come nigh him.

34:30 And Aaron and the children of Israel saw it, and were afraid - It not only dazzled their eyes, but struck such an awe upon them as obliged them to retire. Probably they doubted whether it was a token of God's favour, or of his displeasure.

30. they were afraid to come nigh him-Their fear arose from a sense of guilt-the beaming radiance of his countenance made him appear to their awe-struck consciences a flaming minister of heaven.

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.
