II Thessalonians 3:6-9

But we command you, brethren, in the name of our Lord Jesus Christ, that you withdraw from every brother who walks disorderly and not according to the tradition which he received from us. For you yourselves know how you ought to follow us, for we were not disorderly among you; nor did we eat anyone’s bread free of charge, but worked with labor and toil night and day, that we might not be a burden to any of you, not because we do not have authority, but to make ourselves an example of how you should follow us.
