Luke 17:16 - Ellicott's Commentary On The Whole Bible

And he was a Samaritan. — As in the parable of the Good Samaritan, St. Luke’s purpose in the selection of the incident falls in with what may be called the Catholicity of his Gospel, the breaking down of every middle wall of partition that divided the Jew from the other nations of the world. As the narrative is peculiar to his record, we may reasonably believe that it was one of the facts with which he became acquainted in the course of his personal inquiries in Galilee and Samaria. It is significant, in this case, that the barrier had been already broken down for a time by the common pressure of calamity, but no enduring sense of fellowship had as yet taken its place. The nine would seem to have separated themselves from the Samaritan as soon as they were cleansed. Men want more than the “misery” which our common proverb associates with “strange” companions, before they learn the lesson of brotherhood in its fulness.
