Exodus 16:22-24

22On the sixth day they gathered twice as much bread, two omers each. And when all the leaders of the congregation came and told Moses,

23he said to them, "This is what the Lord has commanded: 'Tomorrow is a day of solemn rest, a holy Sabbath to the Lord; bake what you will bake and boil what you will boil, and all that is left over lay aside to be kept till the morning.'"

24So they laid it aside till the morning, as Moses commanded them, and it did not stink, and there were no worms in it.
