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.

38. I sent you, &c.—The I is emphatic—I, the Lord of the whole harvest: "sent you," points to their past appointment to the apostleship, though it has reference only to their future discharge of it, for they had nothing to do with the present ingathering of the Sycharites.

ye bestowed no labour—meaning that much of their future success would arise from the preparation already made for them. (See on [1780]Joh 4:42).

others laboured—Referring to the Old Testament laborers, the Baptist, and by implication Himself, though He studiously keeps this in the background, that the line of distinction between Himself and all His servants might not be lost sight of. "Christ represents Himself as the Husbandman [rather the Lord of the laborers], who has the direction both of the sowing and of the harvest, who commissions all the agents—those of the Old Testament as well as of the New—and therefore does not stand on a level with either the sowers or the reapers" [Olshausen].
