'Manna' in the Bible

He humbled you by letting you go hungry; then He gave you manna to eat, which you and your fathers had not known, so that you might learn that man does not live on bread alone but on every word that comes from the mouth of the Lord.

He fed you in the wilderness with manna that your fathers had not known, in order to humble and test you, so that in the end He might cause you to prosper.
