Acts 9:26-28

26 Back in Jerusalem he tried to join the disciples, but they were all afraid of him. They didn't trust him one bit.

27 Then Barnabas took him under his wing. He introduced him to the apostles and stood up for him, told them how Saul had seen and spoken to the Master on the Damascus Road and how in Damascus itself he had laid his life on the line with his bold preaching in Jesus' name.

28 After that he was accepted as one of them, going in and out of Jerusalem with no questions asked, uninhibited as he preached in the Master's name.
