Acts 16:4-10 NRSV
As they went from town to town, they delivered to them for observance the decisions that had been reached by the apostles and elders who were in Jerusalem. So the churches were strengthened in the faith and increased in numbers daily.
They went through the region of Phrygia and Galatia, having been forbidden by the Holy Spirit to speak the word in Asia. When they had come opposite Mysia, they attempted to go into Bithynia, but the Spirit of Jesus did not allow them; so, passing by Mysia, they went down to Troas. During the night Paul had a vision: there stood a man of Macedonia pleading with him and saying, “Come over to Macedonia and help us.” When he had seen the vision, we immediately tried to cross over to Macedonia, being convinced that God had called us to proclaim the good news to them.
