16:23 Here is a plain intimation of the observing 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. If the sabbath had now been first instituted, how could Moses have understood what God said to him, Ex 16:4, 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, Ex 16:22, even to the surprize of the rulers, before Moses had declared that it was done with 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.
16:22-31 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, Ge 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.
