12 And let limits be marked out for the people round the mountain, and say to them, Take care not to go up the mountain or near the sides of it: whoever puts his foot on the mountain will certainly come to his death: 13 He is not to be touched by a hand, but is to be stoned or have an arrow put through him; man or beast, he is to be put to death: at the long sounding of a horn they may come up to the mountain.
Matthew Henry's Commentary on Exodus 19:12-13
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.
