Exodus 16:7-10

7and in the morning you will see the glory of the Lord, because he has heard your grumbling against him. Who are we, that you should grumble against us?”

8Moses also said, “You will know that it was the Lord when he gives you meat to eat in the evening and all the bread you want in the morning, because he has heard your grumbling against him. Who are we? You are not grumbling against us, but against the Lord.”

9Then Moses told Aaron, “Say to the entire Israelite community, ‘Come before the Lord, for he has heard your grumbling.’ ”

10While Aaron was speaking to the whole Israelite community, they looked toward the desert, and there was the glory of the Lord appearing in the cloud.
