Then said the woman of Samaria unto him, How is it that you, being a Jew, ask drink of me, who am a woman of Samaria? for the Jews have no dealings with the Samaritans.

Theophylact of Ochrid
AD 1107
Perhaps by His appearance, dress, manner, and speech, the Samaritan woman judged the Lord to be a Jew, which is why she says to Him, How is it that Thou, being a Jew, asketh drink of me? See how circumspect she is. If there were need of caution, the Lord needed it, not her. For it was not that the Samaritans had no dealings with the Jews, but, as she says, that the Jews have no dealings with the Samaritans. None the less, the woman did not keep silent, but out of her concern that the Lord was doing something unlawful for Him to do, she attempted to correct Him. The Lord does not show Who He is until the woman's virtue, prudence, and conscientiousness have first been revealed. Then He begins to speak to her of more profound things. If thou knewest, He says, the gift of God, which means, if you knew what eternal and incorruptible things God gives, and if you also knew that I am God, Who is able to give you these things, you would have asked for and received living water. The Lord calls the gift of the Holy Spirit water because it cleanses and refreshes those who receive it. It is not stagnant, fetid water like that in ponds and wells, but living water, ceaselessly bubbling and gushing upwards. For the grace of the Holy Spirit makes the soul constantly active in doing good, and always ready for spiritual ascents. Of such living and ever active water did the Apostle Paul drink, causing him to forget those things which are behind, and reaching forth unto those which are before. [Phil. 3:13] Then the woman sayeth unto Him, Sir. Do you see how at once she abandons her perception of Him as a man of low rank, and instead adopts great reverence, calling Him "Sir"? However, she has not yet perceived the depth of Christ's words; while He means one thing by the word water, she understands something quite different.
