Exodus 16:8 (KJV)

And Moses and Aaron said unto all the children of Israel, At even, then ye shall know that the Lord hath brought you out from the land of Egypt:

And in the morning, then ye shall see the glory of the Lord; for that he heareth your murmurings against the Lord: and what are we, that ye murmur against us?

And Moses said, This shall be, when the Lord shall give you in the evening flesh to eat, and in the morning bread to the full; for that the Lord heareth your murmurings which ye murmur against him: and what are we? your murmurings are not against us, but against the Lord.

And Moses spake unto Aaron, Say unto all the congregation of the children of Israel, Come near before the Lord: for he hath heard your murmurings.

And it came to pass, as Aaron spake unto the whole congregation of the children of Israel, that they looked toward the wilderness, and, behold, the glory of the Lord appeared in the cloud.
