      Adramyttium--a port on the northeast coast of the Ægean Sea. Doubtless the centurion expected to find another ship, bound for Italy, at some of the ports of Asia Minor, without having to go with this ship all the way to Adramyttium; and in this he was not disappointed. See on Ac 27:6.

      one Aristarchus, a Macedonian of Thessalonica, being with us--rather, "Aristarchus the Macedonian," &c. The word "one" should not have been introduced here by our translators, as if this name had not occurred before; for we find him seized by the Ephesian mob as a "man of Macedonia and Paul's companion in travel" (Ac 19:29) and as a "Thessalonian" accompanying the apostle from Ephesus on his voyage back to Palestine (Ac 20:4). Here both these places are mentioned in connection with his name. After this we find him at Rome with the apostle (Col 4:10; Phm 24).
