1 Thessalonians 4:9-12

Now as to the love of the brethren, you have no need for anyone to write to you, for you yourselves are taught by God to love one another; for indeed you do practice it toward all the brethren who are in all Macedonia. But we urge you, brethren, to excel still more, and to make it your ambition to lead a quiet life and attend to your own business and work with your hands, just as we commanded you, so that you will behave properly toward outsiders and not be in any need.
