Exodus 16:11-13

11And the Lord spoke to Moses, saying, 12“1I have heard the grumblings of the sons of Israel; speak to them, saying, ‘2At twilight you shall eat meat, and in the morning you shall be filled with bread; and 3you shall know that I am the Lord your God.’”

13So it came about at evening that 4the quails came up and covered the camp, and in the morning 5there was a layer of dew around the camp.
