Acts 16:7-10

7And when they came to the border of Mysia, they tried to enter Bithynia, but the Spirit of Jesus would not permit them. 8So they passed by Mysia and went down to Troas.

9During the night, Paul had a vision of a man of Macedonia standing and pleading with him, “Come over to Macedonia and help us.” 10As soon as Paul had seen the vision, we got ready to leave for Macedonia, concluding that God had called us to preach the gospel to them.
