Mattityahu 24:41-43

Orthodox Jewish Bible

⁴¹ Two women are grinding in the mill house, one is snatched away, one is left behind.

⁴² So be shomer, be on your guard, because you do not have daas on which day will be the Bias of [Moshiach] Adoneichem (your L-rd).

⁴³ But understand this: if the Baal Bayit had known in which watch the ganav is coming, he would have stayed awake and would not have allowed his bais to be dug through.
