Catena Aurea on John 4:7–12: John Chrysostom

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.
