1 Thessalonians 4:13-14

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. ¹³But 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. ¹⁴For if we believe that Jesus died and rose again, even so them also which sleep in Jesus will God bring with him. ¹⁵For this we say unto you by the word of the Lord, that we which are alive and remain unto the coming of the Lord shall not prevent them which are asleep. ¹⁶For the Lord himself shall descend from heaven with a shout, with the voice of the archangel, and with the trump of God: and the dead in Christ shall rise first: ¹⁷Then we which are alive and remain shall be caught up together with them in the clouds, to meet the Lord in the air: and so shall we ever be with the Lord.
