'Sad' in the Bible

For if I make you sad, who would be left to make me glad but the one I caused to be sad?

For out of great distress and anguish of heart I wrote to you with many tears, not to make you sad, but to let you know the love that I have especially for you.

For even if I made you sad by my letter, I do not regret having written it (even though I did regret it, for I see that my letter made you sad, though only for a short time).

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.
