Exodus 16:24-27

So they laid it aside till the morning, as Moses commanded them, and it did not stink, and there were no worms in it. Moses said, “Eat it today, for today is a Sabbath to the LORD; today you will not find it in the field. Six days you shall gather it, but on the seventh day, which is a Sabbath, there will be none.” On the seventh day some of the people went out to gather, but they found none.
