John 4:31-38 (NASB)
³¹  Meanwhile the disciples were urging Him, saying, "Rabbi, eat."
³²  But He said to them, "I have food to eat that you do not know about."
³³  So the disciples were saying to one another, "No one brought Him anything to eat, did he?"
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, and then comes the harvest'? Behold, I say to you, lift up your eyes and look on the fields, that they are white for harvest.
³⁶  "Already he who reaps is receiving wages and is gathering fruit for life eternal; so that he who sows and he who reaps may rejoice together.
³⁷  "For in this case the saying is true, 'One sows and another reaps.'
³⁸  "I sent you to reap that for which you have not labored; others have labored and you have entered into their labor."

John 4:39-42 (NASB)
³⁹  From that city many of the Samaritans believed in Him because of the word of the woman who testified, "He told me all the things that I have done."
⁴⁰  So when the Samaritans came to Jesus, they were asking Him to stay with them; and He stayed there two days.
⁴¹  Many more believed because of His word;
⁴²  and they were saying to the woman, "It is no longer because of what you said that we believe, for we have heard for ourselves and know that this One is indeed the Savior of the world."
