1 Thessalonians 4:13; 1 Thessalonians 4:15

13 Now we do not want you to be ignorant, brothers, concerning those who have fallen asleep, so that you will not grieve as also the rest, who have no hope.

15 For this we say to you by the word of the Lord, that we who are alive, who remain until the Lord's coming, will not possibly precede those who have fallen asleep.
