1 Thessalonians 4:11-13

and that ye study to be quiet, and to do your own business, and to work with your own hands, as we commanded you; that ye may walk honestly toward them that are without, and that ye may have lack of nothing. But I would not have you to be ignorant, brethren, concerning them which are asleep, that ye sorrow not, even as others which have no hope.
