22 And on the sixth day they took up twice as much of the bread, two omers for every person: and all the rulers of the people gave Moses word of it. 23 And he said, This is what the Lord has said, Tomorrow is a day of rest, a holy Sabbath to the Lord: what has to be cooked may be cooked; and what is over, put on one side to be kept till the morning. 24 And they kept it till the morning as Moses had said: and no smell came from it, and it had no worms. 25 And Moses said, Make your meal today of what you have, for this day is a Sabbath to the Lord: today you will not get any in the fields. 26 For six days you will get it, but on the seventh day, the Sabbath, there will not be any. 27 But still on the seventh day some of the people went out to get it, and there was not any. 28 And the Lord said to Moses, How long will you go against my orders and my laws? 29 See, because the Lord has given you the Sabbath, he gives you on the sixth day bread enough for two days; let every man keep where he is; let no man go out of his place on the seventh day. 30 So the people took their rest on the seventh day. 31 And this bread was named manna by Israel: it was white, like a grain seed, and its taste was like cakes made with honey.

Here is mention of a seventh-day sabbath. It was known, not only before the giving of the law upon mount Sinai, but before the bringing of Israel out of Egypt, even from the beginning, Genesis 2:3. The setting apart one day in seven for holy work, and, in order to that, for holy rest, was ever since God created man upon the earth, and is the most ancient of the Divine laws. 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 make it ready. This directs us to contrive family affairs, so that they may hinder us as little as possible in the work of the sabbath. Works of necessity are to be done on that day; but it is desirable to have as little as may be to do, that we may apply ourselves the more closely to prepare for the life that is to come. When they kept manna against a command, it stank; when they kept it by a command, it was sweet and good; every thing is sanctified by the word of God and prayer. On the seventh day God did not send the manna, therefore they must not expect it, nor go out to gather. This showed that it was produced by miracle.
