8 For though I should glory somewhat abundantly concerning our authority (which the Lord gave for building you up, and not for casting you down), I shall not be put to shame: 9 that I may not seem as if I would terrify you by my letters. 10 For, His letters, they say, are weighty and strong; but his bodily presence is weak, and his speech of no account. 11 Let such a one reckon this, that, what we are in word by letters when we are absent, such [are we] also in deed when we are present.
Matthew Henry's Commentary on 2 Corinthians 10:8-11
Commentary on 2 Corinthians 10:7-11
(Read 2 Corinthians 10:7-11)
