2 Corinthians 7:10-11

Noyes(i) 10 For sorrow before God worketh repentance to salvation never to be regretted; but the sorrow of the world worketh death. 11 For behold this very thing, that your sorrow had respect to God; what earnestness it wrought in you; yea, what clearing of yourselves, yea, what indignation, yea, what fear, yea, what longing desire, yea, what zeal, yea, what readiness to punish! In every thing ye showed yourselves to be pure in the matter.
