John: 4:34 Jesus saith unto them, My meat is to do the will of him that sent me, and to finish his work
The word "meat" means "food" and not "meat" in the sense we think of it. Most modern translations render this Greek word, "broma", as "food". Jesus is telling us that he is totally focused on fulfilling his Father's will in his life and the mission that he was called to accomplish. It is more important to him than physical food.
