A.T. Robertson Commentary 2 Corinthians 13:10

"For this cause I write these things while absent, that I may not when present deal sharply, according to the authority which the Lord gave me for building up, and not for casting down." — 2 Corinthians 13:10 (ASV)

That I may not when present deal sharply (ινα παρων αποτομως χρησωμα). Late adverb from αποτομος, curt, cut off. In N.T. only here and Tit 1:13.
