Exodus 16:22-24

22Now on the sixth day they gathered twice as much bread, two omers for each person; and all the leaders of the congregation came and told Moses.

23He said to them, “This is what the Lord has said: ‘Tomorrow is a solemn rest, a holy Sabbath to the Lord’; bake and boil what you will bake and boil [today], and all that remains left over put aside for yourselves to keep until morning.”

24They put it aside until morning, as Moses told them, and it did not become foul nor was it wormy.
