[31]Meanwhile the disciples besought him, saying, "Rabbi, eat."
[32] But he said to them, "I have food to eat of which you do not know."
[33] So the disciples said to one another, "Has any one brought him food?"
[34] Jesus said to them, "My food is to do the will of him who sent me, and to accomplish his work.
[35] Do you not say, `There are yet four months, then comes the harvest'? I tell you, lift up your eyes, and see how the fields are already white for harvest.
[36] He who reaps receives wages, and gathers fruit for eternal life, so that sower and reaper may rejoice together.
[37] For here the saying holds true, `One sows and another reaps.'
[38] I sent you to reap that for which you did not labor; others have labored, and you have entered into their labor."

JOHN Chapter 4 (RSV)
