I have made a fool of myself, but you drove me to it. I ought to have been commended by you, for I am not in the least inferior to the "super-apostles," even though I am nothing.
NIV
Now I have been [speaking like] a fool! But you forced me to it, for I ought to have been [saved the necessity and] commended by you. For I have not fallen short one bit or proved myself at all inferior to those superlative [false] apostles [of yours], even if I am nothing (a nobody).
AMP
I am become a fool in glorying; ye have compelled me: for I ought to have been commended of you: for in nothing am I behind the very chiefest apostles, though I be nothing.
KJV
