2 Corinthians 2:2

2 For if I grieve you, who is left to make me glad but you whom I have grieved?

2 Corinthians 3:1

1 Are we beginning to commend ourselves again? Or do we need, like some people, letters of recommendation to you or from you?

2 Corinthians 12:5

5 I will boast about a man like that, but I will not boast about myself, except about my weaknesses.

2 Corinthians 12:13

13 How were you inferior to the other churches, except that I was never a burden to you? Forgive me this wrong!
