Matthew 24:1-3

As Jesus was leaving the Temple grounds, his disciples pointed out to him the various Temple buildings. But he responded, “Do you see all these buildings? I tell you the truth, they will be completely demolished. Not one stone will be left on top of another!” Later, Jesus sat on the Mount of Olives. His disciples came to him privately and said, “Tell us, when will all this happen? What sign will signal your return and the end of the world?”
