Gaius of Derbe, a city in the Roman province of Galatia in Asia Minor, in the region of Lycaonia, is named as one of Paul’s seven traveling companions who waited for him at Troas
23 Gaius, my host and the host of the whole church, greets you. Erastus, the treasurer of the city, greets you, and Quartus, a brother.
— Rom. 16:23
