Exodus 16:3-7

3The 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.” 4Then the Lord said to Moses, “I will rain down bread from heaven for you. The people are to go out each day and gather enough for that day. In this way I will test them and see whether they will follow my instructions. 5On the sixth day they are to prepare what they bring in, and that is to be twice as much as they gather on the other days.” 6So Moses and Aaron said to all the Israelites, “In the evening you will know that it was the Lord who brought you out of Egypt, 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?”
