Exodus 16:2-3, 8

And the whole congregation of the children of Israel murmured against Moses and Aaron in the wilderness: and the children of Israel said unto them, Would to God we had died by the hand of the LORD in the land of Egypt, when we sat by the flesh pots, and when we did eat bread to the full; for ye have brought us forth into this wilderness, to kill this whole assembly with hunger.

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.
