Discovery Box2 Corinthians 2:10 
Context2:10 If you forgive anyone for anything, I also forgive him – for indeed what I have forgiven (if I have forgiven anything) I did so for you in the presence of Christ,
2 Corinthians 7:13-14
Context7:13 Therefore we have been encouraged. And in addition to our own encouragement, we rejoiced even more at the joy of Titus, because all of you have refreshed his spirit. 1 7:14 For if I have boasted to him about anything concerning you, I have not been embarrassed by you, 2 but just as everything we said to you was true, 3 so our boasting to Titus about you 4 has proved true as well.
2 Corinthians 12:11
Context12:11 I have become a fool. You yourselves forced me to do it, for I should have been commended by you. For I lack nothing in comparison 5 to those “super-apostles,” even though I am nothing.
2 Corinthians 12:19
Context12:19 Have you been thinking all this time 6 that we have been defending ourselves to you? We are speaking in Christ before God, and everything we do, dear friends, is to build you up. 7
1 tn Or “all of you have put his mind at ease.”
2 tn Grk “I have not been put to shame”; the words “by you” are not in the Greek text but are implied.
3 tn Grk “just as we spoke everything to you in truth.”
4 tn The words “about you” are not in the Greek text but are implied.
5 tn Or “I am in no way inferior.”
6 tc The reading “all this time” (πάλαι, palai) is found in several early and important Alexandrian and Western witnesses including א* A B F G 0243 6 33 81 365 1175 1739 1881 lat; the reading πάλιν (palin, “again”) is read by א2 D Ψ 0278 Ï sy bo; the reading οὐ πάλαι (ou palai) is read by Ì46, making the question even more emphatic. The reading of Ì46 could only have arisen from πάλαι. The reading πάλιν is significantly easier (“are you once again thinking that we are defending ourselves?”), for it softens Paul’s tone considerably. It thus seems to be a motivated reading and cannot easily explain the rise of πάλαι. Further, πάλαι has considerable support in the Alexandrian and Western witnesses, rendering it virtually certain as the original wording here.
7 tn Or “for your strengthening”; Grk “for your edification.”
