The Lord now, by his angel, delivers in an intelligible manner, the ten words, or commandments, which contain the sum of all the natural law, and may be reduced to the two precepts of charity, Matthew xxii. 40; Mark xii. 31. How these commandments are to be divided into ten, the ancients are not perfectly agreed. We follow the authority of St. Augustine, (9. 71,) St. Clement of Alexandria, (strom. 6,) and others, in referring three of the precepts to God, and seven to our neighbour. Protestants adopt the Jewish method, of making four commandments of the first table, and six of the second; as they divide our first into two, and unite the 9th and 10th; though it surely must appear rational to admit a distinct precept, for an internal as well as for an external object; and the desires of committing adultery or theft, require a distinct prohibition no less than the external actions. Whereas the forbidding to have strange gods, or to worship images, or creatures of any description, is exactly of the same tendency. For no one can worship an idol, without admitting a strange god. The latter part, therefore, of the first commandment, or the second of Protestants, is only a farther explanation of what had gone before, as Moses himself clearly insinuates, ver. 23, You shall not make gods of silver, &c.
When Moses and Aaron were gone up, or had passed the bounds of the people, God spake thus out of the mount Horeb, that all the people heard.
The object of man’s worship, Exo 20:1,2. The decalogue, Exo 20:3-17. The people fear, Exo 20:18. They desire Moses to speak to them, and not God, Exo 20:19. Moses encourages them, Exo 20:20. Moses drawing near the darkness, God speaks to him, Exo 20:21,22. God’s charge about making no other gods, Exo 20:23. God’s command to build an altar, and of what they should make it, Exo 20:24,25; and in what manner they should approach unto it, Exo 20:26.
Verses 1-2 God speaks many ways to the children of men; by conscience, by providences, by his voice, to all which we ought carefully to attend; but he never spake at any time so as he spake the TEN COMMANDMENTS. This law God had given to man before; it was written in his heart; but sin so defaced it, that it was necessary to revive the knowledge of it. The law is spiritual, and takes knowledge of the secret thoughts, desires, and dispositions of the heart. Its grand demand is love, without which outward obedience is mere hypocrisy. It requires perfect, unfailing, constant obedience; no law in the world admits disobedience to itself. Whosoever shall keep the whole law, and yet offend in one point, he is guilty of all, ( James 2:10 ) . Whether in the heart or the conduct, in thought, word, or deed, to omit or to vary any thing, is sin, and the wages of sin is death.

Here is, I. The preface of the law-writer, Moses: God spoke all these words, v. 1. The law of the ten commandments is, 1. A law of God's making. They are enjoined by the infinite eternal Majesty of heaven and earth. And where the word of the King of kings is surely there is power. 2. It is a law of his own speaking. God has many ways of speaking to the children of men (Job 33 14); once, yea twice—by his Spirit, by conscience, by providences, by his voice, all which we ought carefully to attend to; but he never spoke, at any time, upon any occasion, as he spoke the ten commandments, which therefore we ought to hear with the more earnest heed. They were not only spoken audibly (so he owned the Redeemer by a voice from heaven, Matt 3 17), but with a great deal of dreadful pomp. This law God had given to man before (it was written in his heart by nature); but sin had so defaced that writing that it was necessary, in this manner, to revive the knowledge of it.
Or, Then, to wit, when Moses was returned into the mount. immediately, and not by an angel. For though an ambassador or messenger may act in the name of his master, yet it is against the use of all ages and places for such to call themselves by his name. As well might an ambassador of France say, I am the king of France, which all men would account absurd, arrogant, and ridiculous, as an angel might say, All these words, i.e. commands, for so the word is used, Deu 17:19 Est 1:12.
II. The preface of the Law-maker: I am the Lord thy God, v. 2. Herein, 1. God asserts his own authority to enact this law in general: "I am the Lord who command thee all that follows." 2. He proposes himself as the sole object of that religious worship which is enjoined in the first four of the commandments. They are here bound to obedience by a threefold cord, which, one would think, could not easily be broken. (1.) Because God is the Lord—Jehovah, self-existent, independent, eternal, and the fountain of all being and power; therefore he has an incontestable right to command us. He that gives being may give law; and therefore he is able to bear us out in our obedience, to reward it, and to punish our disobedience. (2.) He was their God, a God in covenant with them, their God by their own consent; and, if they would not keep his commandments, who would? He had laid himself under obligations to them by promise, and therefore might justly lay his obligations on them by precept. Though that covenant of peculiarity is now no more, yet there is another, by virtue of which all that are baptized are taken into relation to him as their God, and are therefore unjust, unfaithful, and very ungrateful, if they obey him not. (3.) He had brought them out of the land of Egypt; therefore they were bound in gratitude to obey him, because he had done them so great a kindness, had brought them out of a grievous slavery into a glorious liberty. They themselves had been eye-witnesses of the great things God had done in order to their deliverance, and could not but have observed that every circumstance of it heightened their obligation. They were now enjoying the blessed fruits of their deliverance, and in expectation of a speedy settlement in Canaan; and could they think any thing too much to do for him that had done so much for them? Nay, by redeeming them, he acquired a further right to rule them; they owed their service to him to whom they owed their freedom, and whose they were by purchase. And thus Christ, having rescued us out of the bondage of sin, is entitled to the best service we can do him, Luke 1 74. Having loosed our bonds, he has bound us to obey him, Ps 116 16.
