1 Thessalonians 4:15; 1 Thessalonians 5:3

15 For this we say to you by the word of the Lord , that we who are alive and remain until the coming of the Lord , will not precede those who have fallen asleep.
3 While they are saying, "Peace and safety!" then destruction will come upon them suddenly like labor pains upon a woman with child , and they will not escape.
