Asia

When the Bible says Asia, it does not mean the continent. It names a Roman province in what we now call western Turkey, and its cities and churches fill the later New Testament. Jews from Asia are among the crowd at Pentecost in Acts 2:9, and others from there stir up trouble against Paul in the temple. In Revelation 1:4 John writes “to the seven churches which are in Asia”: Ephesus and six more. Paul’s letters send greetings from “the churches of Asia” too. Revelation 2 and 3 take each of the seven in turn, and begin with Ephesus.

From Easton's Bible Dictionary

Matthew George Easton, 1897

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.

From Smith's Bible Dictionary

William Smith, 1884

(orient). The passages in the New Testament where this word occurs are the following; (Acts 2:9; 6:9; 16:6; 19:10,22,26,27; 20:4,16,18; 21:27; 27:2; Romans 16:5; 1 Corinthians 16:19; 2 Corinthians 1:8; 2 Timothy 1:15; 1 Peter 1:1; Revelation 1:4,11) In all these it may be confidently stated that the word is used for a Roman province which embraced the western part of the peninsula of Asia Minor and of which Ephesus was the capital.
