Acts 9:27-29

27But 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.

28So he was with them at Jerusalem, coming in and going out.

29And he spoke boldly in the name of the Lord Jesus and disputed against the Hellenists, but they attempted to kill him.
