Exodus 16:1-8

And they took their journey from Elim, and all the congregation of the children of Israel came unto the wilderness of Sin, which is between Elim and Sinai, on the fifteenth day of the second month after their departing out of the land of Egypt. And the whole congregation of the children of Israel murmured against Moses and against Aaron in the wilderness: and the children of Israel said unto them, Would that we had died by the hand of Jehovah in the land of Egypt, when we sat by the flesh-pots, when we did eat bread to the full; for ye have brought us forth into this wilderness, to kill this whole assembly with hunger. Then said Jehovah unto Moses, Behold, I will rain bread from heaven for you; and the people shall go out and gather a day’s portion every day, that I may prove them, whether they will walk in my law, or not. And it shall come to pass on the sixth day, that they shall prepare that which they bring in, and it shall be twice as much as they gather daily. And Moses and Aaron said unto all the children of Israel, At even, then ye shall know that Jehovah hath brought you out from the land of Egypt; and in the morning, then ye shall see the glory of Jehovah; for that he heareth your murmurings against Jehovah: and what are we, that ye murmur against us? And Moses said, This shall be, when Jehovah shall give you in the evening flesh to eat, and in the morning bread to the full; for that Jehovah heareth your murmurings which ye murmur against him: and what are we? your murmurings are not against us, but against Jehovah.
