Exodus 16:3-4

And the children of Israel said to them, “Oh, that we had died by the hand of the LORD in the land of Egypt, when we sat by the pots of meat and 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 certain quota every day, that I may test them, whether they will walk in My law or not.
