Now when Paul and his company loosed from Paphos, they came to Perga in Pamphylia: and John departing from them returned to Jerusalem.
Note 1 at Ac 13:13: Perga was the capital of the Roman province of Pamphylia (see note 2 at this verse). It was located about 7 miles inland on the Kestros River (modern-day Aksu), or approximately 165 miles northwest of Cyprus.
Note 2 at Ac 13:13: Pamphylia was a Roman province in Asia Minor on the northern coast of the Mediterranean Sea. It was bordered on the west by Lycia, the north by Pisidia, the east by Cilicia, and the south by the Mediterranean Sea. Its two principal cities were Perga (see note 1 at this verse) and Attalia.
Note 3 at Ac 13:13: The Scriptures do not give John Mark's reasons for departing from Paul and Barnabas. We can tell by Paul's reaction in Ac 15:37-39 that Paul didn't consider Mark's reasons for leaving as being very good.
