Exodus 16:23-30

He said to them, “This is what the LORD commanded: ‘Tomorrow is to be a day of sabbath rest, a holy sabbath to the LORD. So bake what you want to bake and boil what you want to boil. Save whatever is left and keep it until morning.’ ” 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. Then the LORD said to Moses, “How long will you refuse to keep my commands and my instructions? Bear in mind that the LORD has given you the Sabbath; that is why on the sixth day he gives you bread for two days. Everyone is to stay where they are on the seventh day; no one is to go out.” So the people rested on the seventh day.
