Exodus 16:25 ASV

²³  And he said unto them, This is that which Jehovah hath spoken, Tomorrow is a solemn rest, a holy sabbath unto Jehovah: bake that which ye will bake, and boil that which ye will boil; and all that remaineth over lay up for you to be kept until the morning.

²⁴  And they laid it up till the morning, as Moses bade: and it did not become foul, neither was there any worm therein.

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

²⁶  Six days ye shall gather it; but on the seventh day is the sabbath, in it there shall be none.

²⁷  And it came to pass on the seventh day, that there went out some of the people to gather, and they found none.
