'Bread' in the Bible

Go then, eat your bread in happiness and drink your wine with a cheerful heart; for God has already approved your works.

I again saw under the sun that the race is not to the swift and the battle is not to the warriors, and neither is bread to the wise nor wealth to the discerning nor favor to men of ability; for time and chance overtake them all.

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