Acts 9:26-27

26 When Saul had come to Jerusalem, he tried to join himself to the disciples; but they were all afraid of him, not believing that he was a disciple.  27 But Barnabas took him, and brought him to the apostles, and declared to them how he had seen the Lord in the way, and that he had spoken to him, and how at Damascus he had preached boldly in the name of Jesus.
