John 4:32-35

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.” As the crowds emerged from the village, Jesus said to his disciples, “Why would you say, ‘The harvest is another four months away’? Look at all the people coming—now is harvest time! Their hearts are like vast fields of ripened grain—ready for a harvest.
