Mark 13:1-4

As He was going out of the temple, one of His disciples *said to Him, “Teacher, behold what wonderful stones and what wonderful buildings!” And Jesus said to him, “Do you see these great buildings? Not one stone will be left upon another which will not be torn down.” As He was sitting on the Mount of Olives opposite the temple, Peter and James and John and Andrew were questioning Him privately, “Tell us, when will these things be, and what will be the sign when all these things are going to be fulfilled?”
