Erastus

Erastus - (Easton's Bible Dictionary)

Beloved. (1.) The "chamberlain" of the city of Corinth (Rom. 16:23), and one of Paul's disciples. As treasurer of such a city he was a public officer of great dignity, and his conversion to the gospel was accordingly a proof of the wonderful success of the apostle's labours.

(2.) A companion of Paul at Ephesus, who was sent by him along with Timothy into Macedonia (Acts 19:22). Corinth was his usual place of abode (2 Tim. 4:20); but probably he may have been the same as the preceding.
