Exodus 16:23-25

23And he said unto them, This is that which the Lord hath said, To morrow is the rest of the holy sabbath unto the Lord: bake that which ye will bake to day, and seethe that ye will seethe; 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 bade: and it did not stink, neither was there any worm therein.

25And Moses said, Eat that to day; for to day is a sabbath unto the Lord: to day ye shall not find it in the field.
