Exodus 16:1-6

Then the whole community of Israel set out from Elim and journeyed into the wilderness of Sin, between Elim and Mount Sinai. They arrived there on the fifteenth day of the second month, one month after leaving the land of Egypt. There, too, the whole community of Israel complained about Moses and Aaron. “If only the LORD had killed us back in Egypt,” they moaned. “There we sat around pots filled with meat and ate all the bread we wanted. But now you have brought us into this wilderness to starve us all to death.” Then the LORD said to Moses, “Look, I’m going to rain down food from heaven for you. Each day the people can go out and pick up as much food as they need for that day. I will test them in this to see whether or not they will follow my instructions. On the sixth day they will gather food, and when they prepare it, there will be twice as much as usual.” So Moses and Aaron said to all the people of Israel, “By evening you will realize it was the LORD who brought you out of the land of Egypt.
