Gaius mine host, and of the whole church, saluteth you. Erastus the chamberlain of the city saluteth you, and Quartus a brother.
Gaius mine host, and (the host) of the whole church, saluteth you - (see Acts 20:4.) It would appear that this Gaius was one of only two persons whom Paul baptized with his own hand (cf. 3 John). His Christian hospitality appears to have been something uncommon.
Erastus the chamberlain (or, 'treasurer') of the city - doubtless the city of Corinth (see Acts 19:22; 2 Timothy 4:20),
Saluteth you, and Quartus a brother, х ho (G3588) adelfos (G80)] - 'the,' or 'our brother,' as Sosthenes and Timothy are called, 1 Corinthians 1:1; 2 Corinthians 1:1 (Greek). Nothing more is known of this Quartus.
Benediction Repeated (Romans 16:24)
