29 Moses came down from Mount Sinai. As he came down from the mountain with the two tablets of the covenant in his hand, Moses did not know that the skin of his face shone because he had been talking with God. 30 When Aaron and all the Israelites saw Moses, the skin of his face was shining, and they were afraid to come near him. 31 But Moses called to them; and Aaron and all the leaders of the congregation returned to him, and Moses spoke with them. 32 Afterward all the Israelites came near, and he gave them in commandment all that the Lord had spoken with him on Mount Sinai. 33 When Moses had finished speaking with them, he put a veil on his face; 34 but whenever Moses went in before the Lord to speak with him, he would take the veil off, until he came out; and when he came out, and told the Israelites what he had been commanded, 35 the Israelites would see the face of Moses, that the skin of his face was shining; and Moses would put the veil on his face again, until he went 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.
