Acts 16:4-9

And as they went on their way through the cities, they delivered them the decrees to keep which had been ordained of the apostles and elders that were at Jerusalem. So the churches were strengthened in the faith, and increased in number daily. And they went through the region of Phrygia and Galatia, having been forbidden of the Holy Spirit to speak the word in Asia; and when they were come over against Mysia, they assayed to go into Bithynia; and the Spirit of Jesus suffered them not; and passing by Mysia, they came down to Troas. And a vision appeared to Paul in the night: There was a man of Macedonia standing, beseeching him, and saying, Come over into Macedonia, and help us.
