Acts 9:27-29

27 But Barnabas took him, brought him to the apostles, and described for them how on the road he had seen the Lord, who had spoken to him, and how in Damascus he had spoken boldly in the name of Jesus.
28 So he went in and out among them in Jerusalem, speaking boldly in the name of the Lord.
29 He spoke and argued with the Hellenists; but they were attempting to kill him.
