'Happy' in the Bible

After all, if I were to grieve you, who should make me happy but the person I am making sad?

This is the very reason I wrote you, so that when I did come I might not be made sad by those who should have made me happy. For I had confidence that all of you would share the joy that I have.

Now I am happy, not because you had such sorrow, but because your sorrow led you to repent. For you were sorry in a godly way, and so you were not hurt by us in any way.

I rejoice that in everything I have [perfect] confidence in you.
