I Thessalonians 5:1-3

¹Now as to the times and the epochs, brethren, you have no need of anything to be written to you. ²For you yourselves know full well that the day of the Lord will come just like a thief in the night. ³While 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.
