29 When Moses came down from Mount Sinai carrying the two Tablets of The Testimony, he didn't know that the skin of his face glowed because he had been speaking with God. 30 Aaron and all the Israelites saw Moses, saw his radiant face, and held back, afraid to get close to him. 31 Moses called out to them. Aaron and the leaders in the community came back and Moses talked with them. 32 Later all the Israelites came up to him and he passed on the commands, everything that God had told him on Mount Sinai. 33 When Moses finished speaking with them, he put a veil over his face, 34 but when he went into the presence of God to speak with him, he removed the veil until he came out. When he came out and told the Israelites what he had been commanded, 35 they would see Moses' face, its skin glowing, and then he would again put the veil on his face until he went back in to speak with God.

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.
