2 Corinthians 2:4-5

When I wrote to you before, I was very troubled and unhappy in my heart, and I wrote with many tears. I did not write to make you sad, but to let you know how much I love you. Someone there among you has caused sadness, not to me, but to all of you. I mean he caused sadness to all in some way. (I do not want to make it sound worse than it really is.)
