Exodus 16:3-4

The Israelites said to them, ‘It would have been better if the LORD had killed us in Egypt! There, we sat round pots with plenty of meat. We ate all the food that we wanted. But now you have brought us into this desert. We are so hungry that we will soon die!’ Then the LORD said to Moses, ‘I will cause bread to fall down from the sky for you like rain. Each day, the people must go out and pick up enough bread for that day. In this way I will test them. I will discover whether they will obey my rules.
