'Food' in the Bible

"I have food to eat," He replied, "of which you do not know."

"My food," said Jesus, "is to be obedient to Him who sent me, and fully to accomplish His work.

Bestow your pains not on the food which perishes, but on the food that remains unto the Life of the Ages--that food which will be the Son of Man's gift to you; for on Him the Father, God, has set His seal."

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

He called to them. "Children," He said, "have you any food there?" "No," they answered.
