Exodus 16:23-25

23And he said to them, This is what Jehovah has said: To-morrow is the rest, the holy sabbath, of Jehovah: bake what ye will bake, and cook what ye will cook; and lay up for yourselves all that remains over, to be kept for the morning.

24And they laid it up for the morning, as Moses had commanded; and it did not stink, neither was there any worm in it.

25And Moses said, Eat it to-day; for to-day is sabbath to Jehovah: to-day ye shall not find it in the field.
