Matthew Poole and continuators on 2 Corinthians 2:12

12 Furthermore, when I came to Troas to preach Christs gospel, and a door was opened unto me of the Lord .

This Troas was either the City, or the whole Country called Troy or Ilium, or the lesser Phrygia. We read of Pauls going thither by Sea from Philippi, Acts 20.6, 7. and of his having been there, 2 Tim. 4.13. He tells us, That the business why he went thither, was to preach the Gospel; for it was not the Apostles business to stay, as fixed Ministers, in any one place, but to carry the Gospel up and down the World to several places; which they did by virtue of their general Commission to Go, preach, and baptize all Nations; though sometimes they had a more special Call and Commission, as Paul had, to go into Macedonia. The door opened, either signifieth the free liberty he had there to preach, or the great success which God gave him in his work; which he elsewhere calleth an Effectual door.
