2 Corinthians 7:8-10

New Catholic Bible

⁸ Even if I did cause you sorrow with my letter, I do not regret it. I did regret this letter briefly, but, having come to realize that you were sorrowful only for a short time, ⁹ I now am able to rejoice, not because you were grieved but because your sorrow led to repentance. For you were sorrowful in a godly way and so received no harm because of us. ¹⁰ Such godly sorrow results in repentance that leads to salvation and causes no regret, whereas worldly sorrow produces death.
