II Corinthians 7:13-16

Therefore we have been comforted in your comfort. And we rejoiced exceedingly more for the joy of Titus, because his spirit has been refreshed by you all. For if in anything I have boasted to him about you, I am not ashamed. But as we spoke all things to you in truth, even so our boasting to Titus was found true. And his affections are greater for you as he remembers the obedience of you all, how with fear and trembling you received him. Therefore I rejoice that I have confidence in you in everything.
