19 "The firstborn of every animal belongs to me, including the firstborn males from your herds of cattle and your flocks of sheep and goats. 20 A firstborn donkey may be bought back from the Lord by presenting a lamb or young goat in its place. But if you do not buy it back, you must break its neck. However, you must buy back every firstborn son. "No one may appear before me without an offering. 21 "You have six days each week for your ordinary work, but on the seventh day you must stop working, even during the seasons of plowing and harvest. 22 "You must celebrate the Festival of Harvest with the first crop of the wheat harvest, and celebrate the Festival of the Final Harvest at the end of the harvest season. 23 Three times each year every man in Israel must appear before the Sovereign, the Lord, the God of Israel. 24 I will drive out the other nations ahead of you and expand your territory, so no one will covet and conquer your land while you appear before the Lord your God three times each year. 25 "You must not offer the blood of my sacrificial offerings together with any baked goods containing yeast. And none of the meat of the Passover sacrifice may be kept over until the next morning. 26 "As you harvest your crops, bring the very best of the first harvest to the house of the Lord your God. "You must not cook a young goat in its mother's milk."

Moses and the Tables of the Law

27 Then the Lord said to Moses, "Write down all these instructions, for they represent the terms of the covenant I am making with you and with Israel."

28 Moses remained there on the mountain with the Lord forty days and forty nights. In all that time he ate no bread and drank no water. And the Lord wrote the terms of the covenant-the Ten Commandments -on the stone tablets. 29 When Moses came down Mount Sinai carrying the two stone tablets inscribed with the terms of the covenant, he wasn't aware that his face had become radiant because he had spoken to the Lord . 30 So when Aaron and the people of Israel saw the radiance of Moses' face, they were afraid to come near him.

Matthew Henry's Commentary on Exodus 34:19-30

Commentary on Exodus 34:18-27

(Read Exodus 34:18-27)

Once a week they must rest, even in ploughing time, and in harvest. All worldly business must give way to that holy rest; even harvest work will prosper the better, for the religious observance of the sabbath day in harvest time. We must show that we prefer our communion with God, and our duty to him, before the business or the joy of harvest. Thrice a year they must appear before the Lord God, the God of Israel. Canaan was a desirable land, and the neighbouring nations were greedy; yet God says, They shall not desire it. Let us check all sinful desires against God and his glory, in our hearts, and then trust him to check all sinful desires in the hearts of others against us. The way of duty is the way of safety. Those who venture for him never lose by him. Three feasts are here mentioned: 1. The Passover, in remembrance of the deliverance out of Egypt. 2. The feast of weeks, or the feast of Pentecost; added to it is the law of the first-fruits. 3. The feast of in-gathering, or the feast of Tabernacles. Moses is to write these words, that the people might know them better. We can never be enough thankful to God for the written word. God would make a covenant with Israel, in Moses as a mediator. Thus the covenant of grace is made with believers through Christ.

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.
