“That I may not seem as if I would terrify you by letters.”
King James Version (KJV)
10:9 I say this, that I may not seem to terrify you by letters - Threatening more than I can perform.
2Co 10:9,10 That I may not seem as if I would terrify you by letters. His enemies said that his letters were weighty and stern, but his presence was very different. In other words, he terrified by empty threats.
