Exodus 16:1-5

On the fifteenth day of the second month after they had left Egypt, the whole company of Israel moved on from Elim to the Wilderness of Sin which is between Elim and Sinai. The whole company of Israel complained against Moses and Aaron there in the wilderness. The Israelites said, “Why didn’t GOD let us die in comfort in Egypt where we had lamb stew and all the bread we could eat? You’ve brought us out into this wilderness to starve us to death, the whole company of Israel!” GOD said to Moses, “I’m going to rain bread down from the skies for you. The people will go out and gather each day’s ration. I’m going to test them to see if they’ll live according to my Teaching or not. On the sixth day, when they prepare what they have gathered, it will turn out to be twice as much as their daily ration.”
