Acts 9:26-27

26When he arrived in Jerusalem, he tried to join the disciples; but they were all afraid of him, not believing that he really was a disciple.

27However, Barnabas took him and brought him to the apostles, and described to them how Saul had seen the Lord on the road [to Damascus], and how He had spoken to him, and how at Damascus Saul had preached openly and spoken confidently in the name of Jesus.
