Exodus 16:25

And 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.

And they laid it up till the morning, as Moses bade: and it did not stink, neither was there any worm therein.

Six days ye shall gather it; but on the seventh day, which is the sabbath, in it there shall be none.

And it came to pass, that there went out some of the people on the seventh day for to gather, and they found none.
