I am not of their mind, who think that this woman understood our Saviour speaking about spiritual water, only she had a mind to talk; and indeed it is hard to conceive how a woman of her education, and way of life, should understand any such thing; but it is plain that she did not understand him in what he was discoursing about, but doth, as it were, deride him, believing that he had no such thing to bestow. She taketh no notice of the water which our Saviour had spoken of, springing up to eternal life; but regarding only the present life, and her ease in that, desires favour of Christ only to supply her wants in this life, and that she might live more at ease: so true is that of the apostle, Romans 8:5, They that are after the flesh do mind the things of the flesh.
