John 4:39

And many of the Samaritans of that city,.... Of Sychar, which was a city of Samaria;

believed on him; that he was the true Messiah he had told the woman he was; and she put it to them whether he was or not: before they saw him, or had any conversation with him themselves, they believed in him; see John 20:29;

for the saying of the woman which testified, he told me all that ever I did: the account she gave was so plain, and honest, and disinterested, that they could not but give credit to it; and since the person was an utter stranger to her, and yet had laid before her the whole series of her past life and conversation, they concluded he could be no other than the Messiah, who should tell all things; and being of quick understanding or smell, was able to disclose the secrets of men.
