Since you seek a proof of Christ speaking in me, who toward you is not weak, but is mighty in you.
All Commentaries on 2 Corinthians 13:3 Go To 2 Corinthians 13
George Leo Haydock
Do you seek a proof? By the Greek it signifies for you, or in your regard. The sense is, that he has left me power enough to chastise those among you who shall deserve it, when I come. (Witham)
I do not know why you delay your conversion. Can you doubt whether it is God who speaks to you by my mouth, who has great power among you, and who is very capable of punishing you. (Bible de Vence)
