Acts 16:10-13

10And when he had seen the vision, straightway we sought to go forth into Macedonia, concluding that God had called us to preach the gospel unto them.

11Setting sail therefore from Troas, we made a straight course to Samothrace, and the day following to Neapolis; 12and from thence to Philippi, which is a city of Macedonia, the first of the district, a Roman colony: and we were in this city tarrying certain days. 13And on the sabbath day we went forth without the gate by a river side, where we supposed there was a place of prayer; and we sat down, and spake unto the women that were come together.
