Acts 16:12-15
16:12 and from there to Philippi, which is a leading city of that district of Macedonia, a Roman colony. We stayed in this city for some days.
16:13 On the Sabbath day we went outside the city gate to the side of the river, where we thought there would be a place of prayer, and we sat down and began to speak to the women who had assembled there.
16:14 A woman named Lydia, a dealer in purple cloth from the city of Thyatira, a God-fearing woman, listened to us. The Lord opened her heart to respond to what Paul was saying.
16:15 After she and her household were baptized, she urged us, “If you consider me to be a believer in the Lord, come and stay in my house.” And she persuaded us.
