Kehillah in Corinth II 10:8-10

Orthodox Jewish Bible

⁸ Now even if I should glory a little too much [2C 12:6] in our samchut (authority) [as Shlichim of Moshiach] [2C 13:10] which Rebbe, Melech HaMoshiach Adoneinu gave for building you up and not for tearing you down, I will make good my claim. [Jer1:10]

⁹ I did not intend to seem as if my iggrot were meant to frighten you.

¹⁰ For they say, "His iggrot indeed are weighty and strong but his physical presence is weak and his shprach (diction), as far as rhetoric is concerned, is despicable."
