Acts 9:26-30

And when Saul had come to Jerusalem, he tried to join the disciples; but they were all afraid of him, and did not believe that he was a disciple. But Barnabas took him and brought him to the apostles. And he declared to them how he had seen the Lord on the road, and that He had spoken to him, and how he had preached boldly at Damascus in the name of Jesus. So he was with them at Jerusalem, coming in and going out. And he spoke boldly in the name of the Lord Jesus and disputed against the Hellenists, but they attempted to kill him. When the brethren found out, they brought him down to Caesarea and sent him out to Tarsus.
