Exodus 16:7-10

7and in the morning you will see the LORD’s glory, because He has heard your grumbling against Him. For who are we, that you should grumble against us?”

8And Moses added, “The LORD will give you meat to eat this evening and bread to fill you in the morning, for He has heard your grumbling against Him. Who are we? Your grumblings are not against us but against the LORD.”

9Then Moses said to Aaron, “Tell the whole congregation of Israel, ‘Come before the LORD, for He has heard your grumbling.’”

10And as Aaron was speaking to the whole congregation of Israel, they looked toward the desert, and there in a cloud the glory of the LORD appeared.
