2 Corinthians 10:9 in the King James Version
That I may not seem as if I would terrify you by letters.
Context
8 For even if I boast somewhat abundantly concerning our authority, which the Lord gave for building you up and not for casting you down, I will not be ashamed,
9 that I may not seem as if I desire to terrify you by my letters.
10 For, “His letters”, they say, “are weighty and strong, but his bodily presence is weak, and his speech is despised.”
