Exodus 16:8, 12-13

Moses said, “This will happen when the LORD gives you meat to eat in the evening, and bread to the full in the morning; for the LORD hears your grumblings which you grumble against Him. And what are we? Your grumblings are not against us but against the LORD.”

“I have heard the grumblings of the sons of Israel; speak to them, saying, ‘At twilight you shall eat meat, and in the morning you shall be filled with bread; and you shall know that I am the LORD your God.’ ” So it came about at evening that the quails came up and covered the camp, and in the morning there was a layer of dew around the camp.
