2 Corinthians 7:8

6Nevertheless God, that comforteth those that are cast down, comforted us by the coming of Titus;

7And not by his coming only, but by the consolation wherewith he was comforted in you, when he told us your earnest desire, your mourning, your fervent mind toward me; so that I rejoiced the more.

8For though I made you sorry with a letter, I do not repent, though I did repent: for I perceive that the same epistle hath made you sorry, though it were but for a season.

9Now I rejoice, not that ye were made sorry, but that ye sorrowed to repentance: for ye were made sorry after a godly manner, that ye might receive damage by us in nothing.

10For godly sorrow worketh repentance to salvation not to be repented of: but the sorrow of the world worketh death.
