10 Then the Lord said to Moses, "Go to the people and consecrate them today and tomorrow, and let them wash their clothes. 11 And let them be ready for the third day. For on the third day the Lord will come down upon Mount Sinai in the sight of all the people. 12 You shall set bounds for the people all around, saying, 'Take heed to yourselves that you do not go up to the mountain or touch its base. Whoever touches the mountain shall surely be put to death. 13 Not a hand shall touch him, but he shall surely be stoned or shot with an arrow; whether man or beast, he shall not live.' When the trumpet sounds long, they shall come near the mountain." 14 So Moses went down from the mountain to the people and sanctified the people, and they washed their clothes. 15 And he said to the people, "Be ready for the third day; do not come near your wives."

16 Then it came to pass on the third day, in the morning, that there were thunderings and lightnings, and a thick cloud on the mountain; and the sound of the trumpet was very loud, so that all the people who were in the camp trembled. 17 And Moses brought the people out of the camp to meet with God, and they stood at the foot of the mountain. 18 Now Mount Sinai was completely in smoke, because the Lord descended upon it in fire. Its smoke ascended like the smoke of a furnace, and the whole mountain quaked greatly. 19 And when the blast of the trumpet sounded long and became louder and louder, Moses spoke, and God answered him by voice. 20 Then the Lord came down upon Mount Sinai, on the top of the mountain. And the Lord called Moses to the top of the mountain, and Moses went up. 21 And the Lord said to Moses, "Go down and warn the people, lest they break through to gaze at the Lord, and many of them perish. 22 Also let the priests who come near the Lord consecrate themselves, lest the Lord break out against them." 23 But Moses said to the Lord, "The people cannot come up to Mount Sinai; for You warned us, saying, 'Set bounds around the mountain and consecrate it.' " 24 Then the Lord said to him, "Away! Get down and then come up, you and Aaron with you. But do not let the priests and the people break through to come up to the Lord, lest He break out against them." 25 So Moses went down to the people and spoke to them.

Matthew Henry's Commentary on Exodus 19:10-25

Commentary on Exodus 19:9-15

(Read Exodus 19:9-15)

The solemn manner in which the law was delivered, was to impress the people with a right sense of the Divine majesty. Also to convince them of their own guilt, and to show that they could not stand in judgment before God by their own obedience. In the law, the sinner discovers what he ought to be, what he is, and what he wants. There he learns the nature, necessity, and glory of redemption, and of being made holy. Having been taught to flee to Christ, and to love him, the law is the rule of his obedience and faith.

Commentary on Exodus 19:16-25

(Read Exodus 19:16-25)

Never was there such a sermon preached, before or since, as this which was preached to the church in the wilderness. It might be supposed that the terrors would have checked presumption and curiosity in the people; but the hard heart of an unawakened sinner can trifle with the most terrible threatenings and judgments. In drawing near to God, we must never forget his holiness and greatness, nor our own meanness and pollution. We cannot stand in judgment before him according to his righteous law. The convinced transgressor asks, What must I do to be saved? and he hears the voice, Believe in the Lord Jesus Christ, and thou shalt be saved. The Holy Ghost, who made the law to convince of sin, now takes of the things of Christ, and shows them to us. In the gospel we read, Christ hath redeemed us from the curse of the law, being made a curse for us. We have redemption through his blood, even the forgiveness of sins. Through him we are justified from all things, from which we could not be justified by the law of Moses. But the Divine law is binding as a rule of life. The Son of God came down from heaven, and suffered poverty, shame, agony, and death, not only to redeem us from its curse, but to bind us more closely to keep its commands.
