Exodus 16:1-5

The whole Israelite community left Elim and came to the Desert of Sin, which was between Elim and Sinai; they arrived there on the fifteenth day of the second month after they had left Egypt. Then the whole Israelite community grumbled to Moses and Aaron in the desert. They 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 and all the food we wanted. But you have brought us into this desert to starve us to death.” Then the LORD said to Moses, “I will cause food to fall like rain from the sky for all of you. Every day the people must go out and gather what they need for that day. I want to see if the people will do what I teach them. On the sixth day of each week, they are to gather twice as much as they gather on other days. Then they are to prepare it.”
