Luke, in describing the regions from which the Jews had come to Jerusalem at the time of Pentecost in the year 33 C.E., lists Asia along with the provinces of Cappadocia, Pontus, and Pamphylia. (Ac 2:9, 10; compare 1Pe 1:1.) He there lists Phrygia apart from Asia, as he does again at Acts 16:6. Pliny the Elder, Roman author of the first century C.E., did likewise. (Natural History, V, XXVIII, 102) The account at Acts 16:6, 7 states that Paul was “forbidden by the holy spirit to speak the word in the district of Asia” when traveling westward on his second missionary tour (c. 49-52 C.E.). He therefore moved through Phrygia and Galatia northward toward the province of Bithynia, but he was again diverted westward through Mysia to the seaport of Troas, the natural point for embarking to Macedonia. Here Paul received his vision inviting him to “step over into Macedonia and help us.” (Ac 16:9) So, whereas Paul actually passed through the northern part of the province of Asia, he did not spend time there until his return trip after completing his work in Macedonia and Achaia. He then spent a short time in Ephesus, preaching in the synagogue and, at his departure, promised to return.​—Ac 18:19-21.
