As touching our brother Apollos,.... Who was a senior man to Timothy, an eloquent preacher, one who had been at Corinth, and was well known to the saints there, and greatly approved by many of them; wherefore the apostle excuses it, that he should send the one, and not the other, and shows that it was no fault of his: for, says he,I greatly desired him to come unto you with the brethren; who seem to be Timotheus and Erastus, see Ac 19:22.
He greatly importuned him to go along with them, knowing how acceptable he would be among them, and hoping he might be of great use to them in composing their differences, and rectifying their disorders.
