Do thy diligence to come before winter. Eubulus greeteth thee, and Pudens, and Linus, and Claudia, and all the brethren.

People's New Testament

4:21 Come before winter. He could not come in the winter because navigation was suspended.

Eubulus. Not before mentioned. It is probable that all these were Roman brethren.

Prudens. He is thought to have been a Roman senator, from data secured outside the New Testament.

Linus. A Linus appears as a bishop of Rome not many years later.

Claudia. It has been argued that this lady was the daughter of a British king, and the wife of Prudens. See Conybeare and Howson.

Jamieson-Fausset-Brown Bible Commentary

21. before winter-when a voyage, according to ancient usages of navigation, would be out of the question: also, Paul would need his "cloak" against the winter (2Ti 4:13).

Pudens . Claudia-afterwards husband and wife (according to Martial [Epigrams, 4.13; 11.54]), he a Roman knight, she a Briton, surnamed Rufina. Tacitus [On Agriculture, 14], mentions that territories in southeast Britain were given to a British king; Cogidunus, in reward for his fidelity to Rome, A.D. 52, while Claudius was emperor. In 1772 a marble was dug up at Chichester, mentioning Cogidunus with the surname Claudius, added from his patron, the emperor's name; and Pudens in connection with Cogidunus, doubtless his father-in-law. His daughter would be Claudia, who seems to have been sent to Rome for education, as a pledge of the father's fidelity. Here she was under the protection of Pomponia, wife of Aulus Plautius, conqueror of Britain. Pomponia was accused of foreign superstitions, A.D. 57 [Tacitus, Annals, 3.32], probably Christianity. She probably was the instrument of converting Claudia, who took the name Rufina from her, that being a cognomen of the Pomponian gens (compare Ro 16:13, Rufus, a Christian). Pudens in Martial and in the Chichester inscription, appears as a pagan; but perhaps he or his friends concealed his Christianity through fear. Tradition represents Timothy, a son of Pudens, as taking part in converting the Britons.

Linus-put third; therefore not at this time yet, as he was afterwards, bishop. His name being here inserted between Pudens and Claudia, implies the two were not yet married. "Eubulus" is identified by some with Aristobulus, who, with his converts, is said to have been among the first evangelists of Britain. Paul himself, says Clement, "visited the farthest west [perhaps Britain, certainly Spain], and was martyred under the rulers at Rome," who were Nero's vicegerents in his absence from the city.

Matthew Henry's Concise Commentary

4:19-22 We need no more to make us happy, than to have the Lord Jesus Christ with our spirits; for in him all spiritual blessings are summed up. It is the best prayer we can offer for our friends, that the Lord Jesus Christ may be with their spirits, to sanctify and save them, and at last to receive them to himself. Many who believed as Paul, are now before the throne, giving glory to their Lord: may we be followers of them.
