Exodus 16:24 (KJV)

And Moses said, Let no man leave of it till the morning.

Notwithstanding they hearkened not unto Moses; but some of them left of it until the morning, and it bred worms, and stank: and Moses was wroth with them.

And they gathered it every morning, every man according to his eating: and when the sun waxed hot, it melted.

And it came to pass, that on the sixth day they gathered twice as much bread, two omers for one man: and all the rulers of the congregation came and told Moses.

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

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.

And the LORD said unto Moses, How long refuse ye to keep my commandments and my laws?

See, for that the LORD 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.
