2 Corinthians 2:3

2:3 And I wrote this very thing to you, so that when I came I would not have sadness from those who ought to make me rejoice, since I am confident in you all that my joy would be yours.

2 Corinthians 7:9

7:9 Now I rejoice, not because you were made sad, but because you were made sad to the point of repentance. For you were made sad as God intended, so that you were not harmed in any way by us.
