'Matter' in the Bible

For consider how much diligence this very thing—this grieving as God wills—has produced in you: what a desire to clear yourselves, what indignation, what fear, what deep longing, what zeal, what justice! In every way you showed yourselves to be pure in this matter.

But I sent the brothers so our boasting about you in the matter would not prove empty, and so you would be prepared just as I said.

What I say in this matter of boasting, I don’t speak as the Lord would, but foolishly.
