Paul left for his second missionary journey from Jerusalem, in late Autumn 49, after the meeting of the Council of Jerusalem where the circumcision question was debated. On their trip around the Mediterranean Sea, Paul and his companion Barnabas stopped in Antioch where they had a sharp argument about taking John Mark with them on their trips. The book of Acts said that John Mark had left them in a previous trip and gone home. Unable to resolve the dispute, Paul and Barnabas decided to separate; Barnabas took John Mark with him, while Silas joined Paul.
