Exodus 16:23-25

American Standard Version

²³ And he said unto them, This is that which Jehovah hath spoken, To-morrow 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.
