Exodus 16:24-27

So they saved it until morning, as Moses commanded, and it did not stink or get maggots in it. “Eat it today,” Moses said, “because today is a sabbath to the LORD. You will not find any of it on the ground today. Six days you are to gather it, but on the seventh day, the Sabbath, there will not be any.” Nevertheless, some of the people went out on the seventh day to gather it, but they found none.
