Exodus 16:9-12

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.
