2-е Коринфянам 2:3

I wrote this same unto you--namely, that I would not come to you then (Co2 2:1), as, if I were to come then, it would have to be "in heaviness" (causing sorrow both to him and them, owing to their impenitent state). He refers to the first Epistle (compare Co1 16:7; compare Co1 4:19, Co1 4:21; Co1 5:2-7, Co1 5:13). sorrow from them of whom I ought to rejoice--that is, sorrow from their impenitence, when he ought, on the contrary, to have joy from their penitent obedience. The latter happy effect was produced by his first Epistle, whereas the former would have been the result, had he then visited them as he had originally proposed. having confidence . . . that my joy is the joy of you all--trusting that you, too, would feel that there was sufficient reason for the postponement, if it interfered with our mutual joy [ALFORD]. The communion of saints, he feels confident in them "ALL" (his charity overlooking, for the moment the small section of his detractors at Corinth, Co1 13:7), will make his joy (Co2 2:2) their joy.

In this chapter the apostle proceeds in the account of the reasons why he did not come to Corinth (Co2 2:1-4). Then he writes concerning the incestuous person who lay under censure; and gives direction for restoring him, together with the reasons for their so doing (Co2 2:5-11), and afterwards informs them of his labours and success in preaching the gospel in several places (Co2 2:12-17).

2:3-4 After his painful visit (2:1), Paul then wrote a letter with great anguish . . . and many tears that was intended for the Corinthians’ good. That letter (see also 7:8-10) has evidently been lost. But it was effective in bringing about the needed repentance and change.
