Acts 16:10-13

10And when he had seen the vision, we (including Luke) tried to go on into Macedonia at once, concluding that God had called us to preach the gospel to them.

11So setting sail from Troas, we ran a direct course to Samothrace, and the next day [went on] to Neapolis;

12and from there [we came] to Philippi, which is a leading city of the district of Macedonia, a Roman colony. We stayed on in this city for several days;

13and on the Sabbath day we went outside the city gate to the bank of the [Gangites] river, where we thought there would be a place of prayer, and we sat down and began speaking to the women who had come there.
