In a missionary journey through south-central Asia Minor, Paul and Barnabas had several converts in Iconium, Lystra, and Derbe. Then, on their return journey, they chose a worthy man to be in authority in each place.
The Acts refers to those authorities as presbyters. Our Catholic translations leave it as presbyters, while other Christian Bible call them "Elders."
Surprisingly, our English word "priest" is a derivitive of "presbyter." So we are free to say that Paul and Barnabas put priests in charge in each place.
