Verse 14 continues to give background information about this part of the story. The word "they" refers to Paul and his friends Barnabas and John Mark (also called John). (See: [[rc://en/ta/man/translate/writing-background]])
"the city of Antioch in the district of Pisidia." This is different from the city of Antioch that Paul and Barnabas left at the beginning of the chapter.
