Acts 20:6

And we sailed away from Philippi after the days of unleavened bread, and came unto them in Troas in five days; where we tarried seven days.

We ... Here begins again the famous "we" passages of Acts, indicating that the physician Luke, author of this narrative, had rejoined Paul. Luke was to continue with Paul almost constantly throughout the whole time covered by Acts, with the exception of time that Luke used to research material for his Gospel while Paul was imprisoned in Caesarea and also the time he probably used during Paul's Roman imprisonment for the writing of the book of Acts.

To Troas in five days ... This same journey had required only one days' sail (Acts 16:11) in the opposite direction upon the occasion of another crossing; hence the conclusion that the ship encountered unfavorable winds.

Where we tarried seven days ... Presumably, this delay from Tuesday until the following Monday was to enable the missionary group with Paul to observe the Lord's supper with the church in Troas, an inference from the fact that no reason was given for the delay, coupled with the account of the Lord's day meeting in Troas immediately after mentioning the delay.

The days of unleavened bread ... refers to Passover week, and some have supposed that Paul observed the period patriotically; it is far more likely, however, that Luke in these words merely indicated the time of the year.

TROAS

This seaport, situated at the western extremity of Asia, upon or near the site of ancient Troy, was rebuilt by the successors of Alexander the Great who renamed the place Alexandria Troas. The importance of the place in New Testament history derives from its being: (1) the place where Paul met Luke (Acts 16:8-11), (2) the gateway from Asia to Europe where a "door opened" for Paul (2 Corinthians 2:12), (3) the scene of the remarkably important Lord's day services (Acts 20:7-12), and if Blaiklock's deduction is correct, (4) the scene of Paul's final arrest (2 Timothy 4:13). "Why did Paul leave his garment at Troas? Summary and inhuman arrest, apparently, denied him the comfort of adequate clothing."[6]
