1 Thessalonians 4:11-14

and to make it your ambition to lead a quiet life and attend to your own business and work with your hands, just as we commanded you, so that you will behave properly toward outsiders and not be in any need. But we do not want you to be uninformed, brethren, about those who are asleep, so that you will not grieve as do the rest who have no hope. For if we believe that Jesus died and rose again, even so God will bring with Him those who have fallen asleep in Jesus.
