After a long walk with his disciples, Jesus arrives at an intermediate point in Samaria. This region has a long history and features the old well of the old Hebrew patriarch Joseph. Ah, how many memories had been formed at this exact location!
He is tired from the journey and seeks a drink of water. He meets a woman from Samaria who is stopping by to gather water for her family. This is not a typical occasion, and she is startled to see a full rabbinic Jew at this of all places. Perhaps this man is confused or disoriented and doesn't know his whereabouts, although that theory becomes less and less plausible, and she engages with this phenomenal teacher.
Temporarily alone, Jesus seizes a teachable moment in time.
