MATTHEW XXIV, 1-2; MARK XIII, 1-2; LUKE XXI, 5-6. And as Jesus was going out of the temple, his disciples came to him to show him the buildings of the temple, saying: 'Master, behold what stones and what structures.' And Jesus, answering, said: 'Do you see all these buildings? Amen I say to you: days will come in which there shall not be left here one stone upon another that shall not be thrown down.'
