27 And at this point His disciples came, and they marveled that He talked with a woman; yet no one said, "What do You seek?" or, "Why are You talking with her?" 28 The woman then left her waterpot, went her way into the city, and said to the men, 29 "Come, see a Man who told me all things that I ever did. Could this be the Christ?" 30 Then they went out of the city and came to Him. 31 In the meantime His disciples urged Him, saying, "Rabbi, eat." 32 But He said to them, "I have food to eat of which you do not know." 33 Therefore the disciples said to one another, "Has anyone brought Him anything to eat?" 34 Jesus said to them, "My food is to do the will of Him who sent Me, and to finish His work. 35 Do you not say, 'There are still four months and then comes the harvest'? Behold, I say to you, lift up your eyes and look at the fields, for they are already white for harvest! 36 And he who reaps receives wages, and gathers fruit for eternal life, that both he who sows and he who reaps may rejoice together. 37 For in this 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 labors." 39 And many of the Samaritans of that city believed in Him because of the word of the woman who testified, "He told me all that I ever did." 40 So when the Samaritans had come to Him, they urged Him to stay with them; and He stayed there two days. 41 And many more believed because of His own word. 42 Then they said to the woman, "Now we believe, not because of what you said, for we ourselves have heard Him and we know that this is indeed the Christ, the Savior of the world."

Commentary on John 4:27-42
(Read John 4:27-42)
The disciples wondered that Christ talked thus with a Samaritan. Yet they knew it was for some good reason, and for some good end. Thus when particular difficulties occur in the word and providence of God, it is good to satisfy ourselves that all is well that Jesus Christ says and does. Two things affected the woman. The extent of his knowledge. Christ knows all the thoughts, words, and actions, of all the children of men. And the power of his word. He told her secret sins with power. She fastened upon that part of Christ's discourse, many would think she would have been most shy of repeating; but the knowledge of Christ, into which we are led by conviction of sin, is most likely to be sound and saving. They came to him: those who would know Christ, must meet him where he records his name. Our Master has left us an example, that we may learn to do the will of God as he did; with diligence, as those that make a business of it; with delight and pleasure in it. Christ compares his work to harvest-work. The harvest is appointed and looked for before it comes; so was the gospel. Harvest-time is busy time; all must be then at work. Harvest-time is a short time, and harvest-work must be done then, or not at all; so the time of the gospel is a season, which if once past, cannot be recalled. God sometimes uses very weak and unlikely instruments for beginning and carrying on a good work. Our Saviour, by teaching one poor woman, spread knowledge to a whole town. Blessed are those who are not offended at Christ. Those taught of God, are truly desirous to learn more. It adds much to the praise of our love to Christ and his word, if it conquers prejudices. Their faith grew. In the matter of it: they believed him to be the Saviour, not only of the Jews but of the world. In the certainty of it: we know that this is indeed the Christ. And in the ground of it, for we have heard him ourselves.
