Exodus 16:18-28

18 And when they measured it with an omer, he that gathered much had nothing over, and he that gathered little had no lack; they gathered every man according to his eating.
19 And Moses said unto them, Let no man leave of it till the morning.
20 Notwithstanding they hearkened not unto Moses; but some of them left of it until the morning, and it bred worms, and became foul: and Moses was wroth with them.
21 And they gathered it morning by morning, every man according to his eating: and when the sun waxed hot, it melted.
22 And 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.
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.
28 And Jehovah said unto Moses, How long refuse ye to keep my commandments and my laws?
