We have here, 1. A plain intimation of the observing of a seventh day sabbath, not only before the giving of the law upon Mount Sinai, but before the bringing of Israel out of Egypt, and therefore, from the beginning, Gen 2:3. If the sabbath had now been first instituted, how could Moses have understood what God said to him (Exo 16:5), concerning a double portion to be gathered on the sixth day, without making any express mention of the sabbath? And how could the people so readily take the hint (Exo 16:22), even to the surprise of the rulers, before Moses had declared that it was done with a regard to the sabbath, if they had not had some knowledge of the sabbath before? The setting apart of one day in seven for holy work, and, in order to that, for holy rest, was a divine appointment ever since God created man upon the earth, and the most ancient of positive laws. The way of sabbath-sanctification is the good old way. 2. The double provision which God made for the Israelites, and which they were to make for themselves, on the sixth day: God gave them on the sixth day the bread of two days, Exo 16:29. Appointing them to rest on the seventh day, he took care that they should be no losers by it; and none ever will be losers by serving God. On that day they were to fetch in enough for two days, and to prepare it, Exo 16:23. The law was very strict, that they must bake and seeth, the day before, and not on the sabbath day. This does not now make it unlawful for us to dress meat on the Lord's day, but directs us to contrive our family affairs so that they may hinder us as little as possible in the work of the sabbath. Works of necessity, no doubt, are to be done on that day; but it is desirable to have as little as may be to do of things necessary to the life that now is, that we may apply ourselves the more closely to the one thing needful. That which they kept of for their food on the sabbath day did not putrefy, Exo 16:24. When they kept it in opposition to a command (Exo 16:20) it stank; when they kept it in obedience to a command it was sweet and good; for every thing is sanctified by the word of God and prayer. 3. The intermission of the manna on the seventh day. God did not send it then, and therefore they must not expect it, nor go out to gather, Exo 16:25, Exo 16:26. This showed that it was not produced by natural causes, and that it was designed for a confirmation of the divine authority of the law which was to be given by Moses. Thus God took an effectual course to make them remember the sabbath day; they could not forget it, nor the day of preparation for it. Some, it seems, went out on the seventh day, expecting to find manna (Exo 16:27); but they found none, for those that will find must seek in the appointed time: seek the Lord while he may be found. God, upon this occasion, said to Moses, How long refuse you to keep my commandments? Exo 16:28. Why did he say this to Moses? He was not disobedient. No, but he was the ruler of a disobedient people, and God charges it upon him that he might the more warmly charge it upon them, and might take care that their disobedience should not be through any neglect or default of his. It was for going out to seek for manna on he seventh day that they were thus reproved. Note, (1.) Disobedience, even in a small matter, is very provoking. (2.) God is jealous for the honour of his sabbaths. If walking out on the sabbath to seek for food was thus reproved, walking out on that day purely to find our own pleasure cannot be justified.

On the sixth day they gathered twice as much - This they did that they might have a provision for the Sabbath, for on that day no manna fell, Exo 16:26, Exo 16:27. What a convincing miracle was this! No manna fell on the Sabbath! Had it been a natural production it would have fallen on the Sabbath as at other times; and had there not been a supernatural influence to keep it sweet and pure, it would have been corrupted on the Sabbath as well as on other days. By this series of miracles God showed his own power, presence, and goodness, 1. In sending the manna on each of the six days; 2. In sending none on the seventh, or Sabbath; 3. In preserving it from putrefaction when laid up for the use of that day, though it infallibly corrupted if kept over night on any other day.

And he said unto them, this is that which the Lord hath said,.... Which he had said to Moses privately, for as yet he had said it to none else:

tomorrow is the rest of the holy sabbath unto the Lord; according to Jarchi, the rulers asked Moses what this day was, different from other days, that double the quantity should be gathered? from whence, he says, we learn, that Moses had not as yet declared the sabbath to them; and this is indeed the first time we read of one; and though, as there was divine worship before, there must be times for it; but as there was as yet no certain place for worship, so no certain time for it, but as it was appointed by the heads of families, or as more families might agree unto and unite in; at least no day before this appears to be a day of rest from servile labour, as well as for holy use and service:

bake that which ye will bake today, and seethe that ye will seethe; the phrase "today" is not in the text, and not necessarily supplied; the sense being plainly this, that they might take and boil what they would, and dress as much of the manna as they pleased, and eat what they would, but not that they were to bake and boil for the next day; for it is clear, by what follows, that the manna of the next day was not dressed either way, for then it would be no wonder that it did not stink; and as yet the law for not kindling a fire on the sabbath day was not given; and therefore, for aught to the contrary, they might roast or seethe on that day, or eat it as it was, as they themselves thought fit:

and that which remaineth over; what they did not bake, nor seethe, nor eat:

lay up for you to be kept until the morning whereas on other days they were to leave nothing of it till the morning, but destroy it or cast it away, whatever was left uneaten.

at even the quails came up, and covered the camp--This bird is of the gallinaceous kind [that is, relating to the order of heavy-bodied, largely terrestrial birds], resembling the red partridge, but not larger than the turtledove. They are found in certain seasons in the places through which the Israelites passed, being migratory birds, and they were probably brought to the camp by "a wind from the Lord" as on another occasion (Num 11:31).

and in the morning . . . a small round thing . . . manna--There is a gum of the same name distilled in this desert region from the tamarisk, which is much prized by the natives, and preserved carefully by those who gather it. It is collected early in the morning, melts under the heat of the sun, and is congealed by the cold of night. In taste it is as sweet as honey, and has been supposed by distinguished travellers, from its whitish color, time, and place of its appearance, to be the manna on which the Israelites were fed: so that, according to the views of some, it was a production indigenous to the desert; according to others, there was a miracle, which consisted, however, only in the preternatural arrangements regarding its supply. But more recent and accurate examination has proved this gum of the tarfa-tree to be wanting in all the principal characteristics of the Scripture manna. It exudes only in small quantities, and not every year; it does not admit of being baked (Num 11:8) or boiled (Exo 16:23). Though it may be exhaled by the heat and afterwards fall with the dew, it is a medicine, not food--it is well known to the natives of the desert, while the Israelites were strangers to theirs; and in taste as well as in the appearance of double quantity on Friday, none on Sabbath, and in not breeding worms, it is essentially different from the manna furnished to the Israelites.
