Acts 16:6-9
6 And they went through the region of Phrygia and Galatia, having been forbidden of the Holy Spirit to speak the word in Asia;
7 and when they were come over against Mysia, they assayed to go into Bithynia; and the Spirit of Jesus suffered them not;
8 and passing by Mysia, they came down to Troas.
9 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.
