<p>16:12 <em>And from there to Philippi, which is a city of Macedonia, the first of the district, a Roman colony; and we stayed in this city for some days</em>- The teaching, conversion and baptism of the Philippians took only &quot;some days&quot;; the jailer would have at best only had a brief exposure to Paul's message before meeting him in prison. Likewise Paul was only in Thessalonica &quot;two Sabbath days&quot; and in that time he had to work night and day to support himself and his team. The impression is that the pre-baptismal teaching was brief. Colonies were &quot;another Rome transferred to the soil of another country&quot; (Vine). This explains some of the language in the letter to the Philippians, emphasizing that our citizenship is a heavenly one (Phil. 3:20), when Philippi had been established as a &quot;colony&quot; for Roman citizens. </p>
