Acts 16:13-18
13 And on the Sabbath day we went outside the gate to a riverside, where we were supposing that there would be a place of prayer; and we sat down and began speaking to the women who had assembled.
14 A woman named Lydia, from the city of Thyatira, a seller of purple fabrics, a worshiper of God, was listening; and the Lord opened her heart to respond to the things spoken by Paul.
15 And when she and her household had been baptized, she urged us, saying, “If you have judged me to be faithful to the Lord, come into my house and stay.” And she prevailed upon us.
16 It happened that as we were going to the place of prayer, a slave-girl having a spirit of divination met us, who was bringing her masters much profit by fortune-telling.
17 Following after Paul and us, she kept crying out, saying, “These men are bond-servants of the Most High God, who are proclaiming to you the way of salvation.”
18 She continued doing this for many days. But Paul was greatly annoyed, and turned and said to the spirit, “I command you in the name of Jesus Christ to come out of her!” And it came out at that very moment.
