Exodus 16:7-8

16:7 and in the morning you will see the glory of the Lord, because he has heard your murmurings against the Lord. As for us, what are we, that you should murmur against us?”

16:8 Moses said, “You will know this when the Lord gives you meat to eat in the evening and bread in the morning to satisfy you, because the Lord has heard your murmurings that you are murmuring against him. As for us, what are we? Your murmurings are not against us, but against the Lord.”
