1 Thessalonians 4:18 YLT

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;

¹⁸  so, then, comfort ye one another in these words.
