2 Corinthians 13:2

‘I have said before, and I do say before, as when I was present the second time, so now, being absent, to them that have sinned in the past up to now, and to all the rest, that, if I come again, I will not spare.'

Here two witnesses are called on, the past painful visit and the present letter written while absent from them. They are both a warning of what he will do when he comes in view of the continued sinfulness of all of them, not just those who were clearly wrong in the past, but to all, because in one way or another all have sinned. And what he will do is that he ‘will not spare'. There will be no toning down of his intentions.

‘I have said before.' That is, he has already said it before his coming again, when he was present the second time on the painful visit. ‘And I do say before.' I am also now saying it before my coming visit in this letter, which I write while absent. Thus there are two witnesses to what he intends to do, to not spare them when he comes.

‘To them that have sinned in the past up to now, and to all the rest.' His words are spoken to all, both those who have previously sinned and continue to do so, and to all the others as well. For he does not want any to feel that because they had escaped censure previously they would not be involved. In the end almost the whole church was involved, whether by direct sin or by neglect.
