Pontus

a province of Asia Minor, stretching along the southern coast of the Euxine Sea, corresponding nearly to the modern province of Trebizond. In the time of the apostles it was a Roman province. Strangers from this province were at Jerusalem at Pentecost (Acts 2:9), and to "strangers scattered throughout Pontus," among others, Peter addresses his first epistle (1Pet 1:1). It was evidently the resort of many Jews of the Dispersion. Aquila was a native of Pontus (Acts 18:2).
