Exodus 16:21-26

21And they gathered it morning by morning, every man according to his eating: and when the sun waxed hot, it melted.

22And it came to pass, that on the sixth day they gathered twice as much bread, two omers for each one: and all the rulers of the congregation came and told Moses.

23And he said unto them, This is that which the LORD hath spoken, Tomorrow is a solemn rest, a holy sabbath unto the LORD: bake that which ye will bake, and seethe that which ye will seethe; 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 stink, neither was there any worm therein.

25And Moses said, Eat that today; for today is a sabbath unto the LORD: today 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.
