KJV: Therefore I write these things being absent, lest being present I should use sharpness, according to the power which the Lord hath given me to edification, and not to destruction.
NASB: For this reason I am writing these things while absent, so that when present I need not use severity, in accordance with the authority which the Lord gave me for building up and not for tearing down.
KJV: I have confidence in you through the Lord, that ye will be none otherwise minded: but he that troubleth you shall bear his judgment, whosoever he be.
NASB: I have confidence in you in the Lord that you will adopt no other view; but the one who is disturbing you will bear his judgment, whoever he is.
KJV: But God forbid that I should glory, save in the cross of our Lord Jesus Christ, by whom the world is crucified unto me, and I unto the world.
NASB: But may it never be that I would boast, except in the cross of our Lord Jesus Christ, through which the world has been crucified to me, and I to the world.
