A.T. Robertson Commentary Acts 16:11

"Setting sail therefore from Troas, we made a straight course to Samothrace, and the day following to Neapolis;" — Acts 16:11 (ASV)

Setting sail (αναχθεντες). Same word in 13:13 which see.

We made a straight course (ευθυδρομησαμεν). First aorist active indicative of compound verb ευθυδρομεω (in Philo) from adjective ευθυδρομος (in Strabo), running a straight course (ευθυσ, δρομος). In the N.T. only here and 21:1. It is a nautical term for sailing before the wind. Luke has a true feeling for the sea.

To Samothrace (εις Σαμοθραικην). A small island in the Aegean about halfway between Troas and Neapolis.

The day following (τη επιουση). Locative case of time with ημερα (day) to be supplied (7:26; 20:15; 21:18; 23:11). With adverse winds it took five days to make the run of 125 miles (20:6).

To Neapolis (εις Νεαν Πολιν). To New Town (Newton, Naples, Neapolis). The port of Philippi ten miles distant, Thracian, but reckoned as Macedonian after Vespasian.
