1 Thessalonians 5:1-3

New Revised Standard Version Catholic Edition

5 Now concerning the times and the seasons, brothers and sisters,^[a] you do not need to have anything written to you. ² For you yourselves know very well that the day of the Lord will come like a thief in the night. ³ When they say, “There is peace and security,” then sudden destruction will come upon them, as labor pains come upon a pregnant woman, and there will be no escape!
