Macedonia
   in New Testament times, was a Roman province lying north of
   Greece. It was governed by a propraetor with the title of
   proconsul. Paul was summoned by the vision of the "man of
   Macedonia" to preach the gospel there (Acts 16:9). Frequent
   allusion is made to this event (18:5; 19:21; Rom. 15:26; 2 Cor.
   1:16; 11:9; Phil. 4:15). The history of Paul's first journey
   through Macedonia is given in detail in Acts 16:10-17:15. At the
   close of this journey he returned from Corinth to Syria. He
   again passed through this country (20:1-6), although the details
   of the route are not given. After many years he probably visited
   it for a third time (Phil. 2:24; 1 Tim. 1:3). The first convert
   made by Paul in Europe was (Acts 16:13-15) Lydia (q.v.), a
   "seller of purple," residing in Philippi, the chief city of the
   eastern division of Macedonia.
