Acts 16:12
From there we traveled to Philippi, a Roman colony and the leading city of that district of Macedonia. And we stayed there several days — Philippi is described as a Roman colony (Latin: colonia), indicating its status as a settlement of Roman citizens and its governance by Roman law. The phrase leading city (prōtē tēs meridos, first of its district) designates its political prominence. The extended stay (hēmerai tinas) enables relationship-building and establishes the foundation for the Philippian church.
