There went out some of the people - This was an act of willful disobedience. It is remarkable, being the first violation of the express command, that it was not visited by a signal chastisement: the rest and peace of the "holy Sabbath" were not disturbed by a manifestation of wrath.

And it came to pass,.... Perhaps the next seventh day following:

that there went out some of the people for to gather; to gather manna, as on other days; which they did not through want of provision or a greedy appetite, for they had bread every day, and on that day to the full, but to gratify their curiosity, or to see whether the words of Moses stood, as Aben Ezra expresses it, that is, whether what he said was true, or came to pass, that there should be none, and they should not be able to find any on that day, and so it was:

and they found none; no manna; in the places where they used to find it in plenty on other days.

On the seventh day some of the people went out to gather manna, notwithstanding Moses' command, but they found nothing. Whereupon God reproved their resistance to His commands, and ordered them to remain quietly at home on the seventh day. Through the commandments which the Israelites were to keep in relation to the manna, this gift assumed the character of a temptation, or test of their obedience and faith (cf. Exodus 16:4).

And it came to pass, that there {m} went out some of the people on the seventh day for to gather, and they found none.

(m) Their unfaithfulness was so great, that they did exactly the opposite of God's commandment.

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.
