Exodus 16:23-25

23And he said to them, This is that which the LORD hath said, To morrow is the rest of the holy sabbath to the LORD: bake that which ye will bake to day, and boil that ye will boil; and that which remaineth over lay up for you to be kept until the morning. 24And they laid it up till the morning, as Moses ordered: and it did not stink, neither was there any worm in it. 25And Moses said, Eat that to day; for to day is a sabbath to the LORD: to day ye shall not find it in the field.
