Verse 17. But when he was in Rome. What was the employment of Onesiphorus is not known. It may have been that he was a merchant, and had occasion to visit Rome on business. At all events, he was at pains to search out the apostle, and his attention was the more valuable because it cost him trouble to find him. It is not every one, even among professors of religion, who, in a great and splendid city, would be at the trouble to search out a Christian brother, or even a minister, who was a prisoner, and endeavour to relieve his sorrows. This man, so kind to the great apostle, will be among those to whom the Saviour will say, at the final judgment, "I was in prison, and ye came unto me," Mt 25:36.
