Exodus 16:23-25

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.

25Then Moses said, “Eat that today, for today is a Sabbath to the Lord; today you will not find it in the field.
