KJV: For though I should boast somewhat more of our authority, which the Lord hath given us for edification, and not for your destruction, I should not be ashamed:
NASB: For even if I boast somewhat further about our authority, which the Lord gave for building you up and not for destroying you, I will not be put to shame,
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.
