Here is, I. The preface of the law-writer, Moses: God spoke all these words, Exod. 20:1. 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.

II. The preface of the Law-maker: I am the Lord thy God, Exod. 20:2. 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.

III. The law itself. The first four of the ten commandments, which concern our duty to God (commonly called the first table), we have in these verses. It was fit that those should be put first, because man had a Maker to love before he had a neighbour to love; and justice and charity are acceptable acts of obedience to God only when they flow from the principles of piety. It cannot be expected that he should be true to his brother who is false to his God. Now our duty to God is, in one word, to worship him, that is, to give to him the glory due to his name, the inward worship of our affections, the outward worship of solemn address and attendance. This is spoken of as the sum and substance of the everlasting gospel. Rev. 14:7; Worship God.

1. The first commandment concerns the object of our worship, Jehovah, and him only (Exod. 20:3): Thou shalt have no other gods before me. The Egyptians, and other neighbouring nations, had many gods, the creatures of their own fancy, strange gods, new gods; this law was prefixed because of that transgression, and, Jehovah being the God of Israel, they must entirely cleave to him, and not be for any other, either of their own invention or borrowed from their neighbours. This was the sin they were most in danger of now that the world was so overspread with polytheism, which yet could not be rooted out effectually but by the gospel of Christ. The sin against this commandment which we are most in danger of is giving the glory and honour to any creature which are due to God only. Pride makes a god of self, covetousness makes a god of money, sensuality makes a god of the belly; whatever is esteemed or loved, feared or served, delighted in or depended on, more than God, that (whatever it is) we do in effect make a god of. This prohibition includes a precept which is the foundation of the whole law, that we take the Lord for our God, acknowledge that he is God, accept him for ours, adore him with admiration and humble reverence, and set our affections entirely upon him. In the last words, before me, it is intimated, (1.) That we cannot have any other God but he will certainly know it. There is none besides him but what is before him. Idolaters covet secresy; but shall not God search this out? (2.) That it is very provoking to him; it is a sin that dares him to his face, which he cannot, which he will not, overlook, nor connive at. See Ps. 44:20, 21.

2. The second commandment concerns the ordinances of worship, or the way in which God will be worshipped, which it is fit that he himself should have the appointing of. Here is,

(1.) The prohibition: we are here forbidden to worship even the true God by images, Exod. 20:4, 5. [1.] The Jews (at least after the captivity) thought themselves forbidden by this commandment to make any image or picture whatsoever. Hence the very images which the Roman armies had in their ensigns are called an abomination to them (Matt. 24:15), especially when they were set up in the holy place. It is certain that it forbids making any image of God (for to whom can we liken him? Isa. 40:15, 18), or the image of any creature for a religious use. It is called the changing of the truth of God into a lie (Rom. 1:25), for an image is a teacher of lies; it insinuates to us that God has a body, whereas he is an infinite spirit, Hab. 2:18. It also forbids us to make images of God in our fancies, as if he were a man as we are. Our religious worship must be governed by the power of faith, not by the power of imagination. They must not make such images or pictures as the heathen worshipped, lest they also should be tempted to worship them. Those who would be kept from sin must keep themselves from the occasions of it. [2.] They must not bow down to them occasionally, that is, show any sign of respect or honour to them, much less serve them constantly, by sacrifice or incense, or any other act of religious worship. When they paid their devotion to the true God, they must not have any image before them, for the directing, exciting, or assisting of their devotion. Though the worship was designed to terminate in God, it would not please him if it came to him through an image. The best and most ancient lawgivers among the heathen forbade the setting up of images in their temples. This practice was forbidden in Rome by Numa, a pagan prince; yet commanded in Rome by the pope, a Christian bishop, but, in this, anti-christian. The use of images in the church of Rome, at this day, is so plainly contrary to the letter of this command, and so impossible to be reconciled to it, that in all their catechisms and books of devotion, which they put into the hands of the people, they leave out this commandment, joining the reason of it to the first; and so the third commandment they call the second, the fourth the third, etc.; only, to make up the number ten, they divide the tenth into two. Thus have they committed two great evils, in which they persist, and from which they hate to be reformed; they take away from God’s word, and add to his worship.

(2.) The reasons to enforce this prohibition (Exod. 20:5, 6), which are, [1.] God’s jealousy in the matters of his worship: “I am the Lord Jehovah, and thy God, am a jealous God, especially in things of this nature.” This intimates the care he has of his own institutions, his hatred of idolatry and all false worship, his displeasure against idolaters, and that he resents every thing in his worship that looks like, or leads to, idolatry. Jealousy is quicksighted. Idolatry being spiritual adultery, as it is very often represented in scripture, the displeasure of God against it is fitly called jealousy. If God is jealous herein, we should be so, afraid of offering any worship to God otherwise than as he has appointed in his word. [2.] The punishment of idolaters. God looks upon them as haters of him, though they perhaps pretend love to him; he will visit their iniquity, that is, he will very severely punish it, not only as a breach of his law, but as an affront to his majesty, a violation of the covenant, and a blow at the root of all religion. He will visit it upon the children, that is, this being a sin for which churches shall be unchurched and a bill of divorce given them, the children shall be cast out of covenant and communion together with the parents, as with the parents the children were at first taken in. Or he will bring such judgments upon a people as shall be the total ruin of families. If idolaters live to be old, so as to see their children of the third or fourth generation, it shall be the vexation of their eyes, and the breaking of their hearts, to see them fall by the sword, carried captive, and enslaved. Nor is it an unrighteous thing with God (if the parents died in their iniquity, and the children tread in their steps, and keep up false worships, because they received them by tradition from their fathers), when the measure is full, and God comes by his judgments to reckon with them, to bring into the account the idolatries their fathers were guilty of. Though he bear long with an idolatrous people, he will not bear always, but by the fourth generation, at furthest, he will begin to visit. Children are dear to their parents; therefore, to deter men from idolatry, and to show how much God is displeased with it, not only a brand of infamy is by it entailed upon families, but the judgments of God may for it be executed upon the poor children when the parents are dead and gone. [3.] The favour God would show to his faithful worshippers: Keeping mercy for thousands of persons, thousands of generations of those that love me, and keep my commandments. This intimates that the second commandment, though, in the letter of it, it is only a prohibition of false worships, yet includes a precept of worshipping God in all those ordinances which he has instituted. As the first commandment requires the inward worship of love, desire, joy, hope, and admiration, so the second requires the outward worship of prayer and praise, and solemn attendance on God’s word. Note, First, Those that truly love God will make it their constant care and endeavour to keep his commandments, particularly those that relate to his worship. Those that love God, and keep those commandments, shall receive grace to keep his other commandments. Gospel worship will have a good influence upon all manner of gospel obedience. Secondly, God has mercy in store for such. Even they need mercy, and cannot plead merit; and mercy they shall find with God, merciful protection in their obedience and a merciful recompence of it. Thirdly, This mercy shall extend to thousands, much further than the wrath threatened to those that hate him, for that reaches but to the third or fourth generation. The streams of mercy run now as full, as free, and as fresh, as ever.

3. The third commandment concerns the manner of our worship, that it be done with all possible reverence and seriousness, Exod. 20:7. We have here,

(1.) A strict prohibition: Thou shalt not take the name of the Lord thy God in vain. It is supposed that, having taken Jehovah for their God, they would make mention of his name (for thus all people will walk every one in the name of his god); this command gives a needful caution not to mention it in vain, and it is still as needful as ever. We take God’s name in vain, [1.] By hypocrisy, making a profession of God’s name, but not living up to that profession. Those that name the name of Christ, but do not depart from iniquity, as that name binds them to do, name it in vain; their worship is vain (Matt. 15:7-9), their oblations are vain (Isa. 1:11, 13), their religion is vain, Jas. 1:26. [2.] By covenant-breaking; if we make promises to God, binding our souls with those bonds to that which is good, and yet perform not to the Lord our vows, we take his name in vain (Matt. 5:33), it is folly, and God has no pleasure in fools (Eccl. 5:4), nor will he be mocked, Gal. 6:7. [3.] By rash swearing, mentioning the name of God, or any of his attributes, in the form of an oath, without any just occasion for it, or due application of mind to it, but as a by-word, to no purpose at all, or to no good purpose. [4.] By false swearing, which, some think, is chiefly intended in the letter of the commandment; so it was expounded by those of old time. Thou shalt not forswear thyself, Matt. 5:33. One part of the religious regard the Jews were taught to pay to their God was to swear by his name, Deut. 10:20. But they affronted him, instead of doing him honour, if they called him to be witness to a lie. [5.] By using the name of God lightly and carelessly, and without any regard to its awful significancy. The profanation of the forms of devotion is forbidden, as well as the profanation of the forms of swearing; as also the profanation of any of those things whereby God makes himself known, his word, or any of his institutions; when they are either turned into charms and spells, or into jest and sport, the name of God is taken in vain.

(2.) A severe penalty: The Lord will not hold him guiltless; magistrates, who punish other offences, may not think themselves concerned to take notice of this, because it does not immediately offer injury either to private property or the public peace; but God, who is jealous for his honour, will not thus connive at it. The sinner may perhaps hold himself guiltless, and think there is no harm in it, and that God will never call him to an account for it. To obviate this suggestion, the threatening is thus expressed, God will not hold him guiltless, as he hopes he will; but more is implied, namely, that God will himself be the avenger of those that take his name in vain, and they will find it a fearful thing to fall into the hands of the living God.

4. The fourth commandment concerns the time of worship. God is to be served and honoured daily, but one day in seven is to be particularly dedicated to his honour and spent in his service. Here is,

(1.) The command itself (Exod. 20:8): Remember the sabbath day to keep it holy; and (Exod. 20:10), In it thou shalt do no manner of work. It is taken for granted that the sabbath was instituted before; we read of God’s blessing and sanctifying a seventh day from the beginning (Gen. 2:3), so that this was not the enacting of a new law, but the reviving of an old law. [1.] They are told what is the day they must religiously observe—a seventh, after six days’ labour; whether this was the seventh by computation from the first seventh, or from the day of their coming out of Egypt, or both, is not certain: now the precise day was notified to them (Exod. 16:23), and from this they were to observe the seventh. [2.] How it must be observed. First, As a day of rest; they were to do no manner of work on this day in their callings or worldly business. Secondly, As a holy day, set apart to the honour of the holy God, and to be spent in holy exercises. God, by blessing it, had made it holy; they, by solemnly blessing him, must keep it holy, and not alienate it to any other purpose than that for which the difference between it and other days was instituted. [3.] Who must observe it: Thou, and thy son, and thy daughter; the wife is not mentioned, because she is supposed to be one with the husband and present with him, and, if he sanctify the sabbath, it is taken for granted that she will join with him; but the rest of the family are specified. Children and servants must keep the sabbath, according to their age and capacity: in this, as in other instances of religion, it is expected that masters of families should take care, not only to serve the Lord themselves, but that their houses also should serve him, at least that it may not be through their neglect if they do not, Josh. 24:15. Even the proselyted strangers must observe a difference between this day and other days, which, if it laid some restraint upon them then, yet proved a happy indication of God’s gracious purpose, in process of time, to bring the Gentiles into the church, that they might share in the benefit of sabbaths. Compare Isa. 56:6, 7. God takes notice of what we do, particularly what we do on sabbath days, though we should be where we are strangers. [4.] A particular memorandum put upon this duty: Remember it. It is intimated that the sabbath was instituted and observed before; but in their bondage in Egypt they had lost their computation, or were restrained by their task-masters, or, through a great degeneracy and indifference in religion, they had let fall the observance of it, and therefore it was requisite they should be reminded of it. Note, Neglected duties remain duties still, notwithstanding our neglect. It also intimates that we are both apt to forget it and concerned to remember it. Some think it denotes the preparation we are to make for the sabbath; we must think of it before it comes, that, when it does come, we may keep it holy, and do the duty of it.

(2.) The reasons of this command. [1.] We have time enough for ourselves in those six days, on the seventh day let us serve God; and time enough to tire ourselves, on the seventh it will be a kindness to us to be obliged to rest. [2.] This is God’s day: it is the sabbath of the Lord thy God, not only instituted by him, but consecrated to him. It is sacrilege to alienate it; the sanctification of it is a debt. [3.] It is designed for a memorial of the creation of the world, and therefore to be observed to the glory of the Creator, as an engagement upon ourselves to serve him and an encouragement to us to trust in him who made heaven and earth. By the sanctification of the sabbath, the Jews declared that they worshipped the God that made the world, and so distinguished themselves from all other nations, who worshipped gods which they themselves made. [4.] God has given us an example of rest, after six days’ work: he rested the seventh day, took a complacency in himself, and rejoiced in the work of his hand, to teach us, on that day, to take a complacency in him, and to give him the glory of his works, Ps. 92:4. The sabbath began in the finishing of the work of creation, so will the everlasting sabbath in the finishing of the work of providence and redemption; and we observe the weekly sabbath in expectation of that, as well as in remembrance of the former, in both conforming ourselves to him we worship. [5.] He has himself blessed the sabbath day and sanctified it. He has put an honour upon it by setting it apart for himself; it is the holy of the Lord and honourable: and he has put blessings into it, which he has encouraged us to expect from him in the religious observance of that day. It is the day which the Lord hath made, let not us do what we can to unmake it. He has blessed, honoured, and sanctified it, let not us profane it, dishonour it, and level that with common time which God’s blessing has thus dignified and distinguished.
