My Sabbaths ye shall keep - See Clarke's note on Genesis 2:3. See Clarke's note on Exodus 20:8.

Speak thou also unto the children of Israel,.... Notwithstanding all that has been said and ordered concerning making the tabernacle and all things belonging to it; yet this was not to be understood to the violation of the sabbath, or the neglect of that, in which no work was to be done, no, not any relating to the tabernacle and the vessels of it; and though that was to be made, and everything belonging to it, as soon as possible, yet the sabbath was to be observed, and not broken on that account; and this the people of Israel were told of:

saying; verily, or "nevertheless" (q):

my sabbaths ye shall keep not sabbaths of years, as the seventh year and the fiftieth year, but of weeks, expressed by the plural number, because there are many of them in course throughout the year, no less than fifty two; and so the apostle uses the same number, Colossians 2:16 and so do Heathen writers (r):

for it is a sign between me and you, throughout your generations; a token of the covenant between them, of his being their God and they his people in a peculiar sense; seeing they observed the same day as a day of rest now, on which he had rested at the finishing of the works of creation, which other nations of the world did not observe; of his sanctifying and separating them from all other people; for this was not a sign between him and other nations, but between him and the people of Israel only; and was to be observed throughout their ages, as long as their civil and church state lasted, but not through others:

that ye may know that I am the Lord that doth sanctify you; had separated and distinguished them from the rest of the nations of the world; but if this law had been given to all nations, it could not have been a distinguishing sign of them from others; nor could it be known hereby that God had separated them to himself above all people; and this was done that it might be known, not only by them, for the word "ye" is not in the text, but by others, the nations of the world, as Jarchi; that they were a distinct people, having distinct laws from all others, and particularly this.

Speak thou also unto the children of Israel, saying, {f} Verily my sabbaths ye shall keep: for it is a sign between me and you throughout your generations; that ye may know that I am the LORD that doth sanctify you.

(f) Though I command that these works be done, yet I do not want you to break my Sabbath days.

31:13 It is a sign between me and you - The institution of the sabbath was a great instance of God's favour, and a sign that he had distinguished them from all other people: and their religious observance of it, was a great instance of their duty to him. God, by sanctifying this day among them, let them know that he sanctified them, and set them apart for his service, otherwise he would not have revealed to them his holy sabbaths to be the support of religion among them. The Jews by observing one day in seven, after six days labour, testified that they worshipped the God that made the world in six days, and rested the seventh; and so distinguished themselves from other nations, who having first lost the sabbath, the memorial of the creation, by degrees lost the knowledge of the creator, and gave the creature the honour due to him alone.

31:12-17 Orders were now given that a tabernacle should be set up for the service of God. But they must not think that the nature of the work, and the haste that was required, would justify them in working at it on sabbath days. The Hebrew word /shabath/ signifies rest, or ceasing from labour. The thing signified by the sabbath is that rest in glory which remains for the people of God; therefore the moral obligation of the sabbath must continue, till time is swallowed up in eternity.
