Exodus 16:24-27

So they laid it up till morning, as Moses commanded; and it did not stink, nor were there any worms in it. Then Moses said, “Eat that 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, the Sabbath, there will be none.” Now it happened that some of the people went out on the seventh day to gather, but they found none.
