I shall not be foolish (ουκ εσομα αφρων). Apparent contradiction to 2. Corinthians 11:1; 2. Corinthians 11:16. 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).
