Now if Timotheus come,.... The apostle had sent him already, as appears from 1Co 4:17 and he was now gone from him; but whether he might not be prevented by unforeseen incidents in his journey, he could not say; and therefore speaks cautiously of his coming; from whence it is evident, that this epistle was not sent by Timothy, as the subscription to it suggests.
See that he may be with you without fear; should he come to them, the apostle desires they would take care of him, that he might be safe and secure from enemies of every sort, of which there were many at Corinth; who, as they were of a malignant disposition to him, would use a disciple of his ill: and these were not only, or so much, infidels and profane sinners, but false teachers, and the factions under them, and especially they of the circumcision.
