'Food' in the Bible

For his disciples had gone away into the city to buy food.

But he said to them, "I have food to eat that you don't know about."

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

Don't work for the food which perishes, but for the food which remains to eternal life, which the Son of Man will give to you. For God the Father has sealed him."

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