9 And Jehovah said to Moses, Lo, I will come to thee in the cloud's thick darkness, that the people may hear when I speak with thee, and believe thee also for ever. And Moses told the words of the people to Jehovah. 10 And Jehovah said to Moses, Go to the people, and hallow them to-day and to-morrow, and let them wash their clothes; 11 and let them be ready for the third day; for on the third day Jehovah will come down before the eyes of all the people on mount Sinai. 12 And set bounds round about the people, saying, Take heed to yourselves, [not] to go up unto the mountain nor touch the border of it: whatever toucheth the mountain shall certainly be put to death: 13 not a hand shall touch it, but it shall certainly be stoned, or shot through; whether it be a beast or a man, it shall not live. When the long drawn note of the trumpet soundeth, they shall come up to the mountain. 14 And Moses came down from the mountain to the people, and hallowed 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.

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.
