1 Thessalonians 4:16-17 King James Version (KJV)
16 For 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:
17 Then 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.
1 Thessalonians 4:16-17 Amplified Bible (AMP)
16 For the Lord Himself will come down from heaven with a shout of command, with the voice of the [a]archangel and with the [blast of the] trumpet of God, and the dead in Christ will rise first. 17 Then we who are alive and remain [on the earth] will simultaneously be caught up (raptured) together with them [the resurrected ones] in the clouds to meet the Lord in the air, and so we will always be with the Lord!
