Exodus 16:7-8

7And in the morning you shall see the glory of the Lord; for He hears your complaints against the Lord. But what are we, that you complain against us?”

8Also Moses said, “This shall be seen when the Lord gives you meat to eat in the evening, and in the morning bread to the full; for the Lord hears your complaints which you make against Him. And what are we? Your complaints are not against us but against the Lord.”
