Acts 16:6-10

They passed through the Phrygian and Galatian region, having been forbidden by the Holy Spirit to speak the word in Asia; and after they came to Mysia, they were trying to go into Bithynia, and the Spirit of Jesus did not permit them; and passing by Mysia, they came down to Troas. A vision appeared to Paul in the night: a man of Macedonia was standing and appealing to him, and saying, “Come over to Macedonia and help us.” When he had seen the vision, immediately we sought to go into Macedonia, concluding that God had called us to preach the gospel to them.
