2 Corinthians 7:9-11

Young's Literal Translation

⁹ I now do rejoice, not that ye were made sorry, but that ye were made sorry to reformation, for ye were made sorry toward God, that in nothing ye might receive damage from us;

¹⁰ for the sorrow toward God reformation to salvation not to be repented of doth work, and the sorrow of the world doth work death,

¹¹ for, lo, this same thing -- your being made sorry toward God -- how much diligence it doth work in you! but defence, but displeasure, but fear, but longing desire, but zeal, but revenge; in every thing ye did approve yourselves to be pure in the matter.
