Exodus 16:22-24

22And so it was, on the sixth day, that they gathered twice as much bread, two omers for each one. And all the rulers of the congregation came and told Moses.

23Then he said to them, “This is what the Lord has said: ‘Tomorrow is a Sabbath rest, a holy Sabbath to the Lord. Bake what you will bake today, and boil what you will boil; and lay up for yourselves all that remains, to be kept until morning.’ ”

24So they laid it up till morning, as Moses commanded; and it did not stink, nor were there any worms in it.
