2 Corinthians 7:9-10

King James Version

⁹ Now 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.

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