“Then departed Barnabas to Tarsus, for to seek Saul:”
King James Version (KJV)
11:26 And the disciples were first called Christians at Antioch - Here it was that they first received this standing appellation. They were before termed Nazarenes and Galileans.
Ac 11:25 Then departed Barnabas to Tarsus to seek Saul. Seeing the great opening, he knew that Saul was the best man to aid him. His trip to Tarsus is supposed to have been in A.D. 43; Saul to have departed from Jerusalem in A.D. 39; hence to have spent about four years in missionary work in "Syria and Cilicia" (Ac 15:41 Ga 1:21). See PNT "Ac 9:30".
