Matthew, chapter 24, and it begins like this, “And going out, Jesus was departing from the temple, and his disciples came to him to point out to him the buildings of the temple, and he answered and said to them, ‘See you not all these things? Verily I say to you, there shall not be left here a stone upon a stone that shall not be thrown down.’ And as he sat upon the Mount of Olives, his disciples came to him privately saying, ‘Tell us, what shall these things be and what sign of thy coming and of thy conclusion of the age?’”
