Exodus 16:2-3, 7, 9

In the desert the whole community grumbled against Moses and Aaron. The Israelites said to them, “If only we had died by the LORD’s hand in Egypt! There we sat around pots of meat and ate all the food we wanted, but you have brought us out into this desert to starve this entire assembly to death.”

and 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?”

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