12. Philippi . . . the chief--rather, perhaps, "the first"
      city of that part of Macedonia--The meaning appears to be--the first city one comes to, proceeding from Neapolis. The sense given in our version hardly consists with fact.
      a colony--that is, possessing all the privileges of Roman citizenship, and, as such, both exempted from scourging and (in ordinary cases) from arrest, and entitled to appeal from the local magistrate to the emperor. Though the Pisidian Antioch and Troas were also "colonies," the fact is mentioned in this history of Philippi only on account of the frequent references to Roman privileges and duties in the sequel of the chapter.

      Ac 16:12-34. AT PHILIPPI, LYDIA IS GAINED AND WITH HER HOUSEHOLD BAPTIZED--AN EVIL SPIRIT IS EXPELLED, PAUL AND SILAS ARE SCOURGED, IMPRISONED, AND MANACLED, BUT MIRACULOUSLY SET FREE, AND THE JAILER WITH ALL HIS HOUSEHOLD CONVERTED AND BAPTIZED.

      12, 13. we were in that city abiding certain days--waiting till the sabbath came round: their whole stay must have extended to some weeks. As their rule was to begin with the Jews and proselytes, they did nothing till the time when they knew that they would convene for worship.
