1. A Macedonian, who accompanied Paul in his travels, and whose life was in danger at Ephesus, Acts 19:29.

2. A Corinthian convert of Paul, who hospitable entertained the apostle while laboring at Corinth, Romans 16:23 1 Corinthians 1:14.

3. Of Derbe; an attendant of Paul from Corinth, in his last journey to Jerusalem, Acts 20:4.

The third epistle of John is addressed "to the well-beloved Gaius;" whose character for hospitality comports well with that of 2. above. The name was a common one wherever the Romans lived; and yet it is not certain that more than one or two different individuals of this name are spoken of in Scripture.
