Acts 16:9-15

And a vision appeared to Paul in the night: There was a man of Macedonia standing, beseeching him, and saying, Come over into Macedonia, and help us. And 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. Setting sail therefore from Troas, we made a straight course to Samothrace, and the day following to Neapolis; and 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. And 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. And a certain woman named Lydia, a seller of purple, of the city of Thyatira, one that worshipped God, heard us: whose heart the Lord opened to give heed unto the things which were spoken by Paul. And when she was baptized, and her household, she besought us, saying, If ye have judged me to be faithful to the Lord, come into my house, and abide there. And she constrained us.
