Exodus 16:3-4

The sons of Israel said to them, “Would that we had died by the LORD’S hand in the land of Egypt, when we sat by the pots of meat, when we ate bread to the full; for you have brought us out into this wilderness to kill this whole assembly with hunger.” Then the LORD said to Moses, “Behold, I will rain bread from heaven for you; and the people shall go out and gather a day’s portion every day, that I may test them, whether or not they will walk in My instruction.
