'Matter' in the Bible

For behold, this same thing, that you were made sorry in a godly way, what earnest care it worked in you. Yes, what defense, indignation, fear, longing, zeal, and vengeance! In everything you demonstrated yourselves to be pure in the matter.

I thought it necessary therefore to entreat the brothers that they would go before to you, and arrange ahead of time the generous gift that you promised before, that the same might be ready as a matter of generosity, and not of greediness.
