1 Thessalonians 5:2-4

Revised Standard Version

² For you yourselves know well that the day of the Lord will come like a thief in the night. ³ When people say, “There is peace and security,” then sudden destruction will come upon them as travail comes upon a woman with child, and there will be no escape. ⁴ But you are not in darkness, brethren, for that day to surprise you like a thief.
