Exodus 16:10 (KJV)

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.

And the Lord spake unto Moses, saying,

I have heard the murmurings of the children of Israel: speak unto them, saying, At even ye shall eat flesh, and in the morning ye shall be filled with bread; and ye shall know that I am the Lord your God.
