John 4:31-36 ESV
Meanwhile the disciples were urging him, saying, “Rabbi, eat.” But he said to them, “I have food to eat that you do not know about.” So the disciples said to one another, “Has anyone brought him something to eat?” Jesus said to them, “My food is to do the will of him who sent me and to accomplish his work. Do you not say, ‘There are yet four months, then comes the harvest’? Look, I tell you, lift up your eyes, and see that the fields are white for harvest. Already the one who reaps is receiving wages and gathering fruit for eternal life, so that sower and reaper may rejoice together.
