9 Yahweh said to Moses, “Behold, I come to you in a thick cloud, that the people may hear when I speak with you, and may also believe you forever.” Moses told the words of the people to Yahweh. 10 Yahweh said to Moses, “Go to the people, and sanctify them today and tomorrow, and let them wash their garments, 11 and be ready against the third day; for on the third day Yahweh will come down in the sight of all the people on Mount Sinai. 12 You shall set bounds to the people all around, saying, ‘Be careful that you don’t go up onto the mountain, or touch its border. Whoever touches the mountain shall be surely put to death. 13 No hand shall touch him, but he shall surely be stoned or shot through; whether it is animal or man, he shall not live.’ When the trumpet sounds long, they shall come up to the mountain.” 14 Moses went down from the mountain to the people, and sanctified the people; and they washed their clothes. 15 He said to the people, “Be ready by the third day. Don’t have sexual relations with a woman.”

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.
