'Bread' in the Bible

Go, eat your bread with pleasure, and drink your wine with a cheerful heart, for God has already accepted your works.

Again I saw under the sun that the race is not to the swift, or the battle to the strong, or bread to the wise, or riches to the discerning, or favor to the skillful; rather, time and chance happen to all of them.

Send your bread on the surface of the waters,for after many days you may find it.
