19 “All that opens the womb is mine; and all your livestock that is male, the firstborn of cow and sheep. 20 The firstborn of a donkey you shall redeem with a lamb: and if you will not redeem it, then you shall break its neck. All the firstborn of your sons you shall redeem. No one shall appear before me empty. 21 “Six days you shall work, but on the seventh day you shall rest: in plowing time and in harvest you shall rest. 22 “You shall observe the feast of weeks with the first fruits of wheat harvest, and the feast of harvest at the year’s end. 23 Three times in the year all your males shall appear before the Lord Yahweh, the God of Israel. 24 For I will drive out nations before you and enlarge your borders; neither shall any man desire your land when you go up to appear before Yahweh, your God, three times in the year. 25 “You shall not offer the blood of my sacrifice with leavened bread; neither shall the sacrifice of the feast of the Passover be left to the morning. 26 “You shall bring the first of the first fruits of your ground to the house of Yahweh your God.

“You shall not boil a young goat in its mother’s milk.”

Moses and the Tables of the Law

27 Yahweh said to Moses, “Write you these words: for in accordance with these words I have made a covenant with you and with Israel.”

28 He was there with Yahweh forty days and forty nights; he neither ate bread, nor drank water. He wrote on the tablets the words of the covenant, the ten commandments. 29 It happened, when Moses came down from Mount Sinai with the two tablets of the testimony in Moses’ hand, when he came down from the mountain, that Moses didn’t know that the skin of his face shone by reason of his speaking with him. 30 When Aaron and all the children of Israel saw Moses, behold, the skin of his face shone; and 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.
