And from thence to Philippi, which is the chief city of part of Macedonia, a colony. And we were in this city some days conferring together.  And upon the sabbath day, we went forth without the gate by a river side, where it seemed that there was prayer; and sitting down, we spoke to the women that were assembled.  And a certain woman named Lydia, a seller of purple, of the city of Thyatira, one that worshipped God, did hear: whose heart the Lord opened to attend to those things which were said by Paul.  And when she was baptized, and her household, she besought us, saying: If you have judged me to be faithful to the Lord, come into my house, and abide there. And she constrained us.
