Where were Iconium, Derbe, and Lystra located?
Iconium, Derbe, and Lystra were located in Galatia, specifically in the central part of Galatia or Central Asia Minor. Iconium is called a little city in that central region, and Derbe and Lystra are grouped among those places up there in Galatia.
Les explains that in chapter 14 they stop with the little city of Iconium, which again is up in the central part of Galatia. Then they go to Derbe and Lystra, all those places up there in Galatia or Central Asia Minor. Later, when opposition arose, they fled to Lystra and Derbe. At Lystra, certain Jews from Antioch and Iconium persuaded the people, and Paul was stoned and dragged out of the city, supposing he had been dead. The context consistently places these cities in Galatia or Central Asia Minor.
