Exodus 16:24-27

So they put some aside until morning, just as Moses had commanded. And in the morning the leftover food was wholesome and good, without maggots or odor. Moses said, “Eat this food today, for today is a Sabbath day dedicated to the LORD. There will be no food on the ground today. You may gather the food for six days, but the seventh day is the Sabbath. There will be no food on the ground that day.” Some of the people went out anyway on the seventh day, but they found no food.
