Acts Chapter Sixteen

Acts 16:8–10 (ESV)
8So, passing by Mysia, they went down to Troas. 9And a vision appeared to Paul in the night: a man of Macedonia was standing there, urging him and saying, “Come over to Macedonia and help us.” 10And when Paul had seen the vision, immediately we sought to go on into Macedonia, concluding that God had called us to preach the gospel to them.
