Acts 16:4-9

And as they went through the cities, they delivered them the decrees for to keep, that were ordained of the apostles and elders which were at Jerusalem. And so were the churches established in the faith, and increased in number daily. Now when they had gone throughout Phrygia and the region of Galatia, and were forbidden of the Holy Ghost to preach the word in Asia, after they were come to Mysia, they assayed to go into Bithynia: but the Spirit suffered them not. And they passing by Mysia came down to Troas. And a vision appeared to Paul in the night; There stood a man of Macedonia, and prayed him, saying, Come over into Macedonia, and help us.
