Where Did Paul Write Philippians?

The Bible does not tell us precisely where Paul was when he wrote Philippians. Scholars have generally argued for one of three localities: Caesarea, Ephesus, and Rome. The traditional view that he wrote from Rome seems to be the strongest argument, making the most sense of terms like "praetorian" (Phil. 1:13) and "Caesar's household" (Phil. 4:22). If he wrote during the imprisonment mentioned in Acts 28:16, which scholars argue to be the most likely, then he was under house arrest according to that verse. The Bible does not tell us precisely where Paul was at the time.
