John 4:30-36

They went out from the town and were coming to him. In the meanwhile the disciples were asking him, saying, “Rabbi, eat something!” But he said to them, “I have food to eat that you do not know about.” So the disciples began to say to one another, “No one brought him anything to eat, did they?” Jesus said to them, “My food is that I do the will of the one who sent me and complete his work. Do you not say, ‘There are yet four months and the harvest comes’? Behold, I say to you, lift up your eyes and look at the fields, that they are white for harvest already. The one who reaps receives wages and gathers fruit for eternal life, in order that the one who sows and the one who reaps can rejoice together.
