  Asia
     is used to denote Proconsular Asia, a Roman province which
     embraced the western parts of Asia Minor, and of which Ephesus
     was the capital, in Acts 2:9; 6:9; 16:6; 19:10,22; 20:4, 16, 18,
     etc., and probably Asia Minor in Acts 19:26, 27; 21:27; 24:18;
     27:2. Proconsular Asia contained the seven churches of the
     Apocalypse (Rev. 1:11). The "chiefs of Asia" (Acts 19:31) were
     certain wealthy citizens who were annually elected to preside
     over the games and religious festivals of the several cities to
     which they belonged. Some of these "Asiarchs" were Paul's
     friends.
