A Detour on Paul's Journey
In Syrian Antioch Paul began his second missionary journey speaking to Barnabas: "Come, let us make a return visit to see how the brothers are getting on in all the cities where we proclaimed the word of the Lord," (Acts 15:36) referring to the communities he visited and established during his previous journey, the one discussed on the page about stoning. It seems the original plan was to retrace Paul's steps. But when Paul had a vision during the night at Troas, plans changed. According to Luke, the writer of Acts, "During the night Paul had a vision. A Macedonian stood before him and implored him with these words, 'Come over to Macedonia and help us.' ... We sought passage to Macedonia at once" (Acts 16:9-10). And so, they headed west.
This detour lengthened their journey. The entire trip would eventually encompass over fifteen stops across 2,000 miles. All of those miles were covered either on foot or in ancient Roman boats. The expedition most likely took three or four years to complete (Puskas 26).

By the grace of God, their stay in prison was very brief. At midnight, they were freed from prison by an earthquake: "About midnight, while Paul and Silas were praying and singing hymns to God as the prisoners listened, there was suddenly such a severe earthquake that the foundations of the jail shook; all the doors flew open, and the chains of all were pulled loose"
(Acts 16:25-26). Pictured here are the ruins of an ancient prison cell in Philippi. These ruins have long been believed to be the cell from which Paul and Silas escaped after the earthquake. After this incident, the men understandably left Philippi and continued their journey.
