Acts 16:4-9

And as they went through the cities, they delivered to them the decrees to keep, which were determined by the apostles and elders at Jerusalem. So the churches were strengthened in the faith, and increased in number daily. Now when they had gone through Phrygia and the region of Galatia, they were forbidden by the Holy Spirit to preach the word in Asia. After they had come to Mysia, they tried to go into Bithynia, but the Spirit did not permit them. So passing by Mysia, they came down to Troas. And a vision appeared to Paul in the night. A man of Macedonia stood and pleaded with him, saying, “Come over to Macedonia and help us.”
