Acts 16:9

6 And after they had gone through the land of Phrygia and Galatia, the Holy Spirit did not let them take the word into Asia;

7 And having come to Mysia, they made an attempt to go into Bithynia, but the Spirit of Jesus did not let them;

8 And going past Mysia, they came down to Troas.

9 And Paul had a vision in the night; a man of Macedonia came, requesting him, and saying, Come over into Macedonia and give us help.

10 And when he had seen the vision, straight away we made the decision to go into Macedonia, for it seemed certain to us that God had sent us to give the good news to them.

11 So, from Troas we went straight by ship to Samothrace and the day after to Neapolis;

12 And from there to Philippi, which is the most important town of Macedonia and a Roman colony: and we were there for some days.
