Art thou greater? - Art thou wiser, or better able to find water, than Jacob was? It seems that she supposed that he meant that he could direct her to some living spring, or to some better well in that region, and that this implied more knowledge or skill than Jacob had. To find water and to furnish a good well was doubtless considered a matter of signal skill and success. It was a subject of great importance in that region. This shows how ready sinners are to misunderstand the words of Christ, and to pervert the doctrines of religion. If she had had any proper anxiety about her soul, she would at least have “suspected” that he meant to direct her thoughts to spiritual objects.
Our father Jacob - The Samaritans were composed partly of the remnant of the ten tribes, and partly of people sent from Chaldea; still, they considered themselves descendants of Jacob.
Which gave us - This was doubtless the tradition, though there is no evidence that it was true.
And drank thereof ... - This was added in commendation of the water of the well. A well from which Jacob, and his sons, and cattle had drank must be pure, and wholesome, and honored, and quite as valuable as any that Jesus could furnish. People like to commend that which their ancestors used as superior to anything else. The world over, people love to speak of that which their ancestors have done, and boast of titles and honors that have been handed down from them, even if it is nothing better than existed here - because Jacob’s cattle had drunk of the water.
