'Matter' in the Bible

For behold what earnestness this very thing, this godly sorrow, has produced in you: what vindication of yourselves, what indignation, what fear, what longing, what zeal, what avenging of wrong! In everything you demonstrated yourselves to be innocent in the matter.

I give my opinion in this matter, for this is to your advantage, who were the first to begin a year ago not only to do this, but also to desire to do it.

But what I am doing I will continue to do, so that I may cut off opportunity from those who desire an opportunity to be regarded just as we are in the matter about which they are boasting.
