2 Thessalonians 3:12-14

12Now such people we command and exhort in the Lord Jesus Christ to settle down and work quietly and earn their own food and other necessities [supporting themselves instead of depending on the hospitality of others].

13And as for [the rest of] you, believers, do not grow tired or lose heart in doing good [but continue doing what is right without weakening].

14Now if anyone [in the church] does not obey what we say in this letter, take special note of that person and do not associate with him, so that he will be ashamed and repent.
