Exodus 16:22-26

Now 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. He 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.” They put it aside until morning, as Moses told them, and it did not become foul nor was it wormy. 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 [in the field].”
