Exodus 16:3-4

The Israelites said to them, “It would have been better if the Lord had killed us in the land of Egypt. There we had meat to eat. We had all the food we wanted. But you have brought us into this desert. You will starve us to death here.” Then the Lord said to Moses, “I will cause food to fall like rain from the sky. This food will be for all of you. Every day the people must go out and gather what they need for that day. I will do this to see if the people will do what I teach them.
