Rom13:4 For he is the servant of God to you for good. But if you do evil, have fear; for the sword is not in his hand for nothing: he is God's servant, making God's punishment come on the evil-doer.
1Ts4:6 And that no man may make attempts to get the better of his brother in business: for the Lord is the judge in all these things, as we said to you before and gave witness.
