Matthew 24:2

One stone] Josephus, an eyewitness, says 'Cæsar (i.e. Titus) now gave orders to demolish the whole city and temple, except the highest towers and the west wall. All the rest was so thoroughly laid even with the ground by those that dug it up to the foundation, that there was left nothing to make those who came thither believe that it had ever been inhabited.' The Talmud says, 'On the ninth day of Ab (July-Aug.) the city of Jerusalem was ploughed up.'
