ex 16:2-5
Here in the desert the whole Israelite community grumbled against Moses and Aaron. The Israelites said to them, "Would that we had died at the LORD'S hand in the land of Egypt, as we sat by our fleshpots and ate our fill of bread! But you had to lead us into this desert to make the whole community die of famine!" Then the LORD said to Moses, "I will now rain down bread from heaven for you. Each day the people are to go out and gather their daily portion; thus will I test them, to see whether they follow my instructions or not. On the sixth day, however, when they prepare what they bring in, let it be twice as much as they gather on the other days.".
