27 Just then his disciples came. They were astonished that he was speaking with a woman, but no one said, "What do you want?" or, "Why are you speaking with her?" 28 Then the woman left her water jar and went back to the city. She said to the people, 29 "Come and see a man who told me everything I have ever done! He cannot be the Messiah, can he?" 30 They left the city and were on their way to him. 31 Meanwhile the disciples were urging him, "Rabbi, eat something." 32 But he said to them, "I have food to eat that you do not know about." 33 So the disciples said to one another, "Surely no one has brought him something to eat?" 34 Jesus said to them, "My food is to do the will of him who sent me and to complete his work. 35 Do you not say, "Four months more, then comes the harvest'? But I tell you, look around you, and see how the fields are ripe for harvesting. 36 The reaper is already receiving wages and is gathering 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." 39 Many Samaritans from that city believed in him because of the woman's testimony, "He told me everything I have ever done." 40 So when the Samaritans came to him, they asked him to stay with them; and he stayed there two days. 41 And many more believed because of his word. 42 They said to the woman, "It is no longer because of what you said that we believe, for we have heard for ourselves, and we know that this is truly 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.
