“(For his disciples were gone away unto the city to buy meat.)”
John 4:8 — Greek Interlinear
Church Fathers on John 4:8
That this conversation might not appear a violation of His own injunctions against talking to the Samaritans, the Evangelist explains how it arose; viz. for He did not come with the intention beforehand of talking with the woman, but only would not send the woman away, when she had come. There came a woman of Samaria to draw water. Observe, she comes quite by chance.
The woman here is the type of the Church, not yet justified, but just about to be. And it is a part of the resemblance, that she comes from a foreign people. The Samaritans were foreigners, though they were neighbors and in like manner the Church was to come from the Gentiles, and to be alien from the Jewish race.
Jesus says to her, Give me to drink. As man. the labor and heat He had undergone had made Him thirsty.
