Kehillah in Thessalonika I 5:2-4

Orthodox Jewish Bible

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.

⁴ But you, Achim b’Moshiach, are not in choshech that the Yom should overtake you like a ganav.
