A.T. Robertson Commentary 2 Corinthians 12:6

"For if I should desire to glory, I shall not be foolish; for I shall speak the truth: but I forbear, lest any man should account of me above that which he seeth me [to be], or heareth from me." — 2 Corinthians 12:6 (ASV)

I shall not be foolish (ουκ εσομα αφρων). Apparent contradiction to 11:1,16. But he is here speaking of the Paul "caught up" in case he should tell the things heard (condition of the third class, εαν and first aorist subjunctive θελησω).

Of me (εις εμε). To my credit, almost like dative (cf. εν εμο in 1 Corinthians 14:11).
