BLB(i)
8 For if also I have grieved you in the letter, I do not regret it. For even if I did regret it, I see that the letter grieved you, even if for an hour.
9 Now I rejoice, not that you were grieved, but that you were grieved into repentance. For you were grieved according to God, so that you might suffer loss in nothing through us.
10 For grief according to God produces repentance to salvation without regret; but the world’s grief produces death.
