Orthodox Jewish Bible

24 And having exited from the Beis Hamikdash, Rebbe, Melech HaMoshiach departed, and his talmidim approached to show him the buildings of the Beis Hamikdash.

² But he said in reply to them, Do you not see all these things? Omein, I say to you, by no means will be left here one stone upon another, for all will be demolished.
