Exodus 16:13-21

And it came to pass at even, that the quails came up, and covered the camp: and in the morning the dew lay round about the camp. And when the dew that lay was gone up, behold, upon the face of the wilderness a small round thing, small as the hoar-frost on the ground. And when the children of Israel saw it, they said one to another, What is it? for they knew not what it was. And Moses said unto them, It is the bread which Jehovah hath given you to eat. This is the thing which Jehovah hath commanded, Gather ye of it every man according to his eating; an omer a head, according to the number of your persons, shall ye take it, every man for them that are in his tent. And the children of Israel did so, and gathered some more, some less. 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. And Moses said unto them, 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 became foul: and Moses was wroth with them. And they gathered it morning by morning, every man according to his eating: and when the sun waxed hot, it melted.
