Here is, I. A strict command for the sanctification of the sabbath day, Exo 31:13-17. The law of the sabbath had been given them before any other law, by was of preparation (Exo 16:23); it had been inserted in the body of the moral law, in the fourth commandment; it had been annexed to the judicial law (Exo 23:12); and here it is added to the first part of the ceremonial law, because the observance of the sabbath is indeed the hem and hedge of the whole law; where no conscience is made of that, farewell both godliness and honesty; for, in the moral law, it stands in the midst between the two tables. Some suggest that it comes in here upon another account. Orders were now given that a tabernacle should be set up and furnished for the service of God with all possible expedition; but lest they should think that the nature of the work, and the haste that was required, would justify them in working at it on sabbath days, that they might get it done the sooner, this caution is seasonably inserted, Verily, or nevertheless, my sabbaths you shall keep. Though they must hasten the work, yet they must not make more haste than good speed; they must not break the law of the sabbath in their haste: even tabernacle-work must give way to the sabbath-rest; so jealous is God for the honour of his sabbaths. Observe what is here said concerning the sabbath day.

1.The nature, meaning, and intention, of the sabbath, by the declaration of which God puts an honour upon it, and teaches us to value it. Divers things are here said of the sabbath. (1.) It is a sign between me and you (Exo 31:13), and again, Exo 31:17. The institution of the sabbath was a great instance of God's favour to them, and a sign that he had distinguished them from all other people; and their religious observance of the sabbath was a great instance of their duty and obedience to him. God, by sanctifying this day among them, let them know that he sanctified them, and set them apart for himself and his service; otherwise he would not have revealed to them his holy sabbaths, to be the support of religion among them. Or it may refer to the law concerning the sabbath, Keep my sabbaths, that you may know that I the Lord do sanctify you. Note, If God by his grace incline our hearts to keep the law of the fourth commandment, it will be an evidence of a good work wrought in us by his Spirit. If we sanctify God's day, it is a sign between him and us that he has sanctified our hearts: hence it is the character of the blessed man that he keepeth the sabbath from polluting it, Isa 56:2. The Jews, by observing one day in seven, after six days' labour, testified and declared that they worshipped the God who made the world in six days, and rested the seventh; and so distinguished themselves from other nations, who, having first lost the sabbath, which was instituted to be a memorial of the creation, by degrees lost the knowledge of the Creator, and gave that honour to the creature which was due to him alone. (2.) It is holy unto you (Exo 31:14), that is, "It is designed for your benefit as well as for God's honour;" the sabbath was made for man. Or, "It shall be accounted holy by you, and shall so be observed, and you shall look upon it a sacrilege to profane it." (3.) It is the sabbath of rest, holy to the Lord, Exo 31:15. It is separated from common use, and designed for the honour and service of God, and by the observance of it we are taught to rest from worldly pursuits and the service of the flesh, and to devote ourselves, and all we are, have, and can do, to God's glory. (4.) It was to be observed throughout their generations, in every age, for a perpetual covenant. Exo 31:16. This was to be one of the most lasting tokens of that covenant which was between God and Israel.

2.The law of the sabbath. They must keep it (Exo 31:13, Exo 31:14, Exo 31:16), keep it as a treasure, as a trust, observe it and preserve it, keep it from polluting it, keep it up as a sign between God and them, keep it and never part with it. The Gentiles had anniversary-feasts, to the honour of their gods; but it was peculiar to the Jews to have a weekly festival; this therefore they must carefully observe.

3.The reason of the sabbath; for God's laws are not only backed with the highest authority, but supported with the best reason. God's own example is the great reason, Exo 31:17. As the work of creation is worthy to be thus commemorated, so the great Creator is worthy to be thus imitated, by a holy rest, the seventh day, after six days' labour, especially since we hope, in further conformity to the same example, shortly to rest with him from all our labours.

4.The penalty to be inflicted for the breach of this law: "Every one that defileth the sabbath, by doing any work therein but works of piety and mercy, shall be cut off from among his people (Exo 31:14); he shall surely be put to death. Exo 31:15. The magistrate must cut him off the sword of justice if the crime can be proved; if it cannot, or if the magistrate be remiss, and do not do his duty, God will take the work into his own hands, and cut him off by a stroke from heaven, and his family shall be rooted out of Israel." Note, The contempt and profanation of the sabbath day is an iniquity to be punished by the judges; and, if men do not punish it, God will, here or hereafter, unless it be repented of.

II.The delivering of the two tables of testimony to Moses. God had promised him these tables when he called him up into the mount (Exo 24:12), and now, when he was sending him down, he delivered them to him, to be carefully and honourably deposited in the ark, Exo 31:18. 1. The ten commandments which God had spoken upon mount Sinai in the hearing of all the people were now written, in perpetuam rei memoriam - for a perpetual memorial, because that which is written remains. 2. They were written in tables of stone, prepared, not by Moses, as it should seem (for it is intimated, Exo 24:12, that he found them ready written when he went up to the mount), but, as some think, by the ministry of angels. The law was written in tables of stone, to denote the perpetual duration of it (what can be supposed to last longer than that which is written in stone, and laid up?), to denote likewise the hardness of our hearts; one might more easily write in stone than write any thing that is good in our corrupt and sinful hearts. 3. They were written with the finger of God, that is, by his will and power immediately, without the use of any instrument. It is God only that can write his law in the heart; he gives a heart of flesh, and then, by his Spirit, which is the finger of God, he writes his will in the fleshly tables of the heart, Co2 3:3. 4. They were written in two tables, being designed to direct us in our duty both towards God and towards man. 5. They are called tables of testimony, because this written law testified both the will of God concerning them and his good-will towards them, and would be a testimony against them if they were disobedient. 6. They were delivered to Moses, probably with a charge, before he laid them up in the ark, to show them publicly, that they might be seen and read of all men, and so what they had heard with the hearing of the ear might now be brought to their remembrance. Thus the law was given by Moses, but grace and truth came by Jesus Christ.

Rested, and was refreshed - God, in condescension to human weakness, applies to himself here what belongs to man. If a man religiously rests on the Sabbath, both his body and soul shall be refreshed; he shall acquire new light and life.

It is a sign between me and the children of Israel for ever,.... In like sense as the land of Canaan was given them for an everlasting possession; and the covenant of circumcision, and the ordinance of the passover, and the fast on the day of atonement, were for ever; that is, unto the end of the Jewish world and state, at the coming of Christ, when a new world and state of things began, see Gen 17:8.

for in six days the Lord made heaven and earth, and on the seventh day he rested, and was refreshed; which is to be understood figuratively after the manner of men, who ceasing from toil and labour find rest and refreshment; but not really and properly, for as not labour, and weariness, and fatigue, so neither rest nor refreshment can be properly said of God; but this denotes his cessation from the works of creation, though not of providence, and of the delight and pleasure he takes in a view of them; this is observed, not as the foundation of this law, and the reason of its being made, but as an illustration of it, and as an argument, showing the reasonableness of it, and the similarity of it with what God himself had done, and therefore the enjoining of it could not reasonably be objected to. See Gill on Exo 20:11.

Verily my sabbaths ye shall keep--The reason for the fresh inculcation of the fourth commandment at this particular period was, that the great ardor and eagerness, with which all classes betook themselves to the construction of the tabernacle, exposed them to the temptation of encroaching on the sanctity of the appointed day of rest. They might suppose that the erection of the tabernacle was a sacred work, and that it would be a high merit, an acceptable tribute, to prosecute the undertaking without the interruption of a day's repose; and therefore the caution here given, at the commencement of the undertaking, was a seasonable admonition.
