This introduces a new person in the story without giving his name. We know only that he was from Samaria. (See: [[rc://en/ta/man/translate/writing-participants]])

# bound up his wounds, pouring oil and wine on them
He would have put the oil and wine on the wounds first. AT: "he put wine and oil on the wounds and wrapped them with cloth" (See: [[rc://en/ta/man/translate/figs-events]])
Wine was used to clean the wound, and oil was probably used to prevent infection. This can be stated. AT: "pouring oil and wine on them to help heal them" (See: [[rc://en/ta/man/translate/figs-explicit]])
