'Food' in the Bible

But he said to them, "I have food to eat that you know nothing about."

Jesus said to them, "My food is to do the will of the one who sent me and to complete his work.

Do not work for the food that disappears, but for the food that remains to eternal life -- the food which the Son of Man will give to you. For God the Father has put his seal of approval on him."

For my flesh is true food, and my blood is true drink.
