1 Corinthians 16:10 - Ellicott's Commentary On The Whole Bible

Now if Timotheus come... — Timothy and Erastus had been sent (see 1 Corinthians 4:17) by St. Paul to remind the Corinthians of his former teaching, and to rebuke and check those evils of which rumours had reached the ears of the Apostle. As, however, they would travel through Macedonia, delaying en route at the various churches to prepare them for the visit which St. Paul, according to his then intention, purposed paying them after he had been to Corinth, they possibly might not reach Corinth until after this Epistle, which would be carried thither by a more direct route. The Apostle was evidently anxious to know how Timothy would be received by the Corinthians. He was young in years. He was young also in the faith. He had probably a constitutionally weak and timid nature (see 1 Timothy 3:15; 2 Timothy 1:4), and he was of course officially very subordinate to St. Paul. In a Church, therefore, some of whose members had gone so far as to question, if not actually to repudiate the authority even of the Apostle himself, and to depreciate him as compared with the elder Apostles, there was considerable danger for one like Timothy. By reminding the Corinthians of the work in which Timothy is engaged, and of its identity with his own work, the Apostle anticipates and protests against any insult being offered to Timothy, because of what a great English statesman once called, in reference to himself, “the atrocious crime of being a young man.”
