Kehillah in Thessalonika I 5:1-3

Orthodox Jewish Bible

5 But concerning the ittim (times) and the zmanim (seasons), Chaverim, you have no need for you to have anything in writing.

² For you yourselves know very well that the Yom Hashem comes like a ganav balailah (thief in the night).

³ Whenever they say, "Shalom and Bitachon!" then sudden churban (destruction) will come upon them like the chevlei leydah (birth pangs) of the isha with a baby in her womb. And they can certainly not escape.
