Exodus 16:22

Moreover, God bestowed His gift in such a manner, that the Sabbath was sanctified by it, and the way was thereby opened for its sanctification by the law. On the sixth day of the week the quantity yielded was twice as much, viz., two omers for one (one person). When the princes of the congregation informed Moses of this, he said to them, "Let tomorrow be rest (שׁבּתון), a holy Sabbath to the Lord." They were to bake and boil as much as was needed for the day, and keep what was over for the morrow, for on the Sabbath they would find none in the field. They did this, and what was kept for the Sabbath neither stank nor bred worms. It is perfectly clear from this event, that the Israelites were not acquainted with any sabbatical observance at that time, but that, whilst the way was practically opened, it was through the decalogue that it was raised into a legal institution (see Exo 10:8.). שׁבּתון is an abstract noun denoting "rest," and שׁבּי a concrete, literally the observer, from which it came to be used as a technical term for the seventh day of the week, which was to be observed as a day of rest to the Lord.

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, th…
