2 Corinthians 13:9 in the King James Version
For we are glad, when we are weak, and ye are strong: and this also we wish, even your perfection.
Context
8 For we can do nothing against the truth, but for the truth.
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.
