2:1-4 The apostle desired to have a cheerful meeting with them; and he had written in confidence of their doing what was to their benefit and his comfort; and that therefore they would be glad to remove every cause of disquiet from him.

Some detractor may say that this (2Co 2:1) is not my reason for not coming as I proposed; since I showed no scruple in causing "heaviness," or sorrow, in my Epistle (the first Epistle to the Corinthians). But I answer, If I be the one to cause you sorrow, it is not that I have any pleasure in doing so. Nay, my object was that he "who was made sorry by me" (namely, the Corinthians in general, 2Co 2:3; but with tacit reference to the incestuous person in particular) should repent, and so "make me glad," as has actually taken place; "for … who is he then that?" &c.
