2 Corinthians 10:9-11

Young's Literal Translation

⁹ that I may not seem as if I would terrify you through the letters,

¹⁰ `because the letters indeed -- saith one -- [are] weighty and strong, and the bodily presence weak, and the speech despicable.'

¹¹ This one -- let him reckon thus: that such as we are in word, through letters, being absent, such also, being present, [we are] in deed.
