Jamieson, Fausset and Brown on 2 Corinthians 10:2

2. I beseech you--Intimating that, as he can beseech in letters, so he can be severe in their presence.

that I may not be--that I may not have to be bold, &c.

with that confidence--that authoritative sternness.

I think--I am minded to be.

as if we walked according to the flesh--His Corinthian detractors judged of him by themselves, as if he were influenced by fleshly motives, the desire of favor or fear of giving offense, so as not to exercise his authority when present.
