Exodus 16
14 Ref And when the dew that lay was gone up, behold, upon the face of the wilderness a small round thing, small as the hoar-frost on the ground.
15 Ref And when the children of Israel saw it, they said one to another, What is it? For they knew not what it was. And Moses said unto them, It is the bread which Jehovah hath given you to eat.
