acts 9:27 But Barnabas took him, and brought him to the apostles, and declared unto them how he had seen the Lord in the way, and that he had spoken to him, and how he had preached boldly at Damascus in the name of Jesus. - Free Bible Online

      27. But Barnabas . . . brought him to the apostles--that is, to Peter and James; for "other of the apostles saw I none," says he fourteen years after (Ga 1:18, 19). Probably none of the other apostles were there at the time (Ac 4:36). Barnabas being of Cyprus, which was within a few hours' sail of Cilicia, and annexed to it as a Roman province, and Saul and he being Hellenistic Jews and eminent in their respective localities, they may very well have been acquainted with each other before this [HOWSON]. What is here said of Barnabas is in fine consistency with the "goodness" ascribed to him (Ac 11:24), and with the name "son of consolation," given him by the apostles (Ac 4:36); and after Peter and James were satisfied, the disciples generally would at once receive him.
      how he had seen the Lord . . . and he--the Lord.
      had spoken to him--that is, how he had received his commission direct from the Lord Himself.
