"10And indeed ye do it toward all the brethren which are in all Macedonia: but we beseech you, brethren, that ye increase more and more;
11And that ye study to be quiet, and to do your own business, and to work with your own hands, as we commanded you;
12That ye may walk honestly toward them that are without, and that ye may have lack of nothing." (1st Thessalonians 4)
and this important reminder:
"For even when we were with you, this we commanded you, that if any would not work, neither should he eat." (2nd Thessalonians 3:10)
