9 The Lord said to Moses, "I am going to come to you in a dense cloud, so that the people will hear me speaking with you and will always put their trust in you." Then Moses told the Lord what the people had said.

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.
