A.T. Robertson Commentary 1 Corinthians 4:14

"I write not these things to shame you, but to admonish you as my beloved children." — 1 Corinthians 4:14 (ASV)

To shame you (εντρεπων). Literally, shaming you (present active participle of εντρεπω), old verb to turn one on himself either middle or with reflexive pronoun and active, but the reflexive εαυτοις is not expressed here. See on 2 Thessalonians 3:14. The harsh tone has suddenly changed.
