John 4:20 - Ellicott's Commentary On The Whole Bible

Our fathers worshipped. — She gives a sudden turn to the conversation. It is not that the question of worship is the all-engrossing problem of her mind, for which she seeks solution at this prophet’s hands. Such questions hardly came then within the circle of a Samaritan woman’s thoughts, and this woman’s life had not been such as to make her an exception to the rule; but the heart, quivering before the eye that reads it as it never before had read itself, shrinks from the light that is let in upon it. She will speak of anything rather than of self. There is the mountain overhanging them, the theme of many a discussion between Samaritan and Jew; she will ask the prophet to decide that question.
