2 Corinthians 13:10 in the King James Version
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.
Context
9 For we rejoice when we are weak and you are strong. We also pray for this: your becoming perfect.
10 For this cause I write these things while absent, that I may not deal sharply when present, according to the authority which the Lord gave me for building up and not for tearing down.
11 Finally, brothers, rejoice! Be perfected. Be comforted. Be of the same mind. Live in peace, and the God of love and peace will be with you.
