Kehillah in Corinth II 10:9-11

Orthodox Jewish Bible

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."

¹¹ Let such a one consider this: that the dvar we speak through iggrot when absent will become action we will very well do when present! [2C 13:2,10]
