Exodus 16:23-29

23And 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. 24And they laid it up till the morning, as Moses bade: and it did not become foul, neither was there any worm therein. 25And Moses said, Eat that to-day; for to-day is a sabbath unto Jehovah: to-day ye shall not find it in the field. 26Six days ye shall gather it; but on the seventh day is the sabbath, in it there shall be none. 27And it came to pass on the seventh day, that there went out some of the people to gather, and they found none. 28And Jehovah said unto Moses, How long refuse ye to keep my commandments and my laws? 29See, for that Jehovah hath given you the sabbath, therefore he giveth you on the sixth day the bread of two days; abide ye every man in his place, let no man go out of his place on the seventh day.
