Mark 13:1-4

Then as He went out of the temple, one of His disciples said to Him, “Teacher, see what manner of stones and what buildings are here!” And Jesus answered and said to him, “Do you see these great buildings? Not one stone shall be left upon another, that shall not be thrown down.” Now as He sat on the Mount of Olives opposite the temple, Peter, James, John, and Andrew asked Him privately, “Tell us, when will these things be? And what will be the sign when all these things will be fulfilled?”
