Acts 16:8-11

So they passed by Mysia and went down to Troas. During the night Paul had a vision of a man of Macedonia standing and begging him, “Come over to Macedonia and help us.” After Paul had seen the vision, we got ready at once to leave for Macedonia, concluding that God had called us to preach the gospel to them. From Troas we put out to sea and sailed straight for Samothrace, and the next day we went on to Neapolis.
