Exodus 16:8-9

8And Moses said, “This will happen when the Lord gives you meat to eat in the evening, and bread to the full in the morning; for the Lord hears your grumblings which you grumble against Him. And what are we? Your grumblings are 1not against us but against the Lord.”

9Then Moses said to Aaron, “Say to all the congregation of the sons of Israel, ‘2Come forward before the Lord, for He has heard your grumblings.’”
