Acts 16:11

11, 12. An opportunity was offered without delay, for the apostolic company to make the contemplated voyage to Macedonia. (11) "Therefore, setting sail from Troas, we ran by a straight course to Samothrace, and the next day to Neapolis; (12) and thence to Philippi, which is the first city of that part of Macedonia, and a colony. And we abode in that city some days."

Samothrace is an island in the Archipelago, about midway between Troas and Neapolis. Neapolis was a seaport of Macedonia, and the landing place for Philippi. The remark that they sailed to Samothrace, and the next day to Neapolis, shows that they spent the night at Samothrace, which accords with the custom of ancient navigators, who generally cast anchor at night, during coasting voyages, unless the stars were out. This voyage occupied a part of two days.

Philippi was not the chief city of that part of Macedonia, as rendered in the common version, but the first city; by which is meant, either that it was the first which Paul visited, or the first in point of celebrity. I think the latter is the real idea; for it is obvious from the history that this was the first city Paul visited, and of this the reader need not be informed. But it was the first city of that region in point of celebrity, because it was the scene of the great battle in which Brutus and Cassius were defeated by Marc Antony. Thessalonica was then, and is yet, the chief city of Macedonia.

The observant reader will here notice a change in the style of the narrative, which indicates the presence of the writer among the companions of Paul. Hitherto he had spoken of them only in the third person; but when about to leave Troas, he uses the first person plural, saying, "we sought to go forth into Macedonia," and "we ran to Samothrace," etc. It is only by such a change in the pronoun employed, from the third to the first person, and from the first to the third that we can detect the presence or absence of Luke. From this indication we conclude that he first joined the company in the interior of Asia Minor, just previous to entering the city of Troas. The company with whom we are now traveling is composed of Paul and Silas, Timothy and Luke.
