Acts 16:11-14
11 Setting sail therefore from Troas, we made a straight course to Samothrace, and the day following to Neapolis;
12 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.
13 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.
14 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.
