Charles Ellicott Commentary John 4:39

"And from that city many of the Samaritans believed on him because of the word of the woman, who testified, He told me all things that [ever] I did." — John 4:39 (ASV)

Many of the Samaritans of that city believed.—The willingness to receive the truth on the part of the Samaritans is contrasted with the rejection of it on the part of the Jews. They refused the witness of a great prophet; these accept the witness of a woman. Their minds were prepared by the general expectation of the Messiah; and this woman witnesses that Jesus had revealed to her the whole past of her life. There is here a sign they do not question.
