'Matter' in the Bible

and that [in this matter of sexual misconduct] no man shall transgress and defraud his brother because the Lord is the avenger in all these things, just as we have told you before and solemnly warned you.

For indeed you already do practice it toward all the believers throughout Macedonia [by actively displaying your love and concern for them]. But we urge you, brothers and sisters, that you excel [in this matter] more and more,

in every situation [no matter what the circumstances] be thankful and continually give thanks to God; for this is the will of God for you in Christ Jesus.
