The woman then left her waterpot, and went her way into the city, and saith to the men,

Wesley's Notes

4:28 The woman left her water pot - Forgetting smaller things.

Jamieson-Fausset-Brown Bible Commentary

28-30. left her water-pot-How exquisitely natural! The presence of strangers made her feel that it was time for her to withdraw, and He who knew what was in her heart, and what she was going to the city to do, let her go without exchanging a word with her in the hearing of others. Their interview was too sacred, and the effect on the woman too overpowering (not to speak of His own deep emotion) to allow of its being continued. But this one artless touch-that she "left her water-pot"-speaks volumes. The living water was already beginning to spring up within her; she found that man doth not live by bread nor by water only, and that there was a water of wondrous virtue that raised people above meat and drink, and the vessels that held them, and all human things. In short, she was transported, forgot everything but One, and her heart running over with the tale she had to tell, she hastens home and pours it out.

Matthew Henry's Concise Commentary

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.
