1st Thessalonians 4:14

11 and to study to be quiet, and to do your own business, and to work with your own hands, as we did command you,

12 that ye may walk becomingly unto those without, and may have lack of nothing.

13 And I do not wish you to be ignorant, brethren, concerning those who have fallen asleep, that ye may not sorrow, as also the rest who have not hope,

14 for if we believe that Jesus died and rose again, so also God those asleep through Jesus he will bring with him,

15 for this to you we say in the word of the Lord, that we who are living -- who do remain over to the presence of the Lord -- may not precede those asleep,

16 because the Lord himself, in a shout, in the voice of a chief-messenger, and in the trump of God, shall come down from heaven, and the dead in Christ shall rise first,

17 then we who are living, who are remaining over, together with them shall be caught away in clouds to meet the Lord in air, and so always with the Lord we shall be;
