Were waiting for us in Troas (emenon hma en Troiadi). Here again we have "us" for the first time since chapter 16 where Paul was with Luke in Philippi. Had Luke remained all this time in Philippi? We do not know, but he is with Paul now till Rome is reached. The seven brethren of verse 2 Corinthians 4 went on ahead from Philippi to Troas while Paul remained with Luke in Philippi.
