A.T. Robertson Commentary 2 Corinthians 10:8

"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:" — 2 Corinthians 10:8 (ASV)

Somewhat abundantly (περισσοτερον τ). Comparative, "somewhat more abundantly" than I have, in order to show that he is as true a minister of Christ as his accusers are. Concessive (conditional) clause of third class. For εαν τε see Ro 14:8.

I shall not be put to shame (ουκ αισχυνθησομα). As a convicted impostor or pretentious boaster (Plummer). First future passive, singular number (not literary plural as in verse 7).
