John 4:31-34

Then the disciples began to insist that Jesus eat some of the food they brought back with them, saying, “Teacher, you must eat something.” But Jesus told them, “I have eaten a meal you don’t know about.” Puzzled by this, the disciples began to discuss it among themselves, “Did someone already bring him food?” To clarify, Jesus spoke up and said, “My food is to do the will of him who sent me and bring it to completion.”
