1 Thessalonians 4:11-12

And that you use your endeavour to be quiet: and that you do your own business and work with your own hands, as we commanded you: and that you walk honestly towards them that are without: and that you want nothing of any man's.

And we will not have you ignorant brethren, concerning them that are asleep, that you be not sorrowful, even as others who have no hope.
