Matthew Poole and continuators on John 4:39

39 And many of the Samaritans of that City believed on him, for the saying of the woman, which testified, He told me all that ever I did .

That City was Sichem, or Sychar, but it was within the Province of Samaria, from whence it is that they had the name of Samaritans as well as Sichemites: Many of them upon the Testimony of the Woman, That he had told her such secret passages of her Life, as he could not have told her, if he had not been able, if he had pleased, as well to have told her all things, believed on him: That is, they owned him as a Prophet, and agreed to what the Woman said in that particular, and were by it excited to come to see, and further discourse with Christ. This justifieth what our Saviour said, That there was there a People prepared for the Lord, the Fields were white unto the Harvest; that they were thus far wrought upon by the Discourse of a Woman, and she one not of the higest Reputation, and onely telling them, That he had told her all things she had done. Small means have great effects, when Gods time of working is come.
