How did the Romans destroy the Jerusalem temple?
The Romans used much fire, but they did not destroy the temple by fire alone; they literally dismantled it rock by rock and stone by stone. According to legendary accounts, Roman soldiers had heard that tons of gold were hidden between the building blocks, so they took it down stone by stone.
Les explains that this fulfilled Jesus' prophecy that not one stone would be left upon another. He contrasts the Romans with Nebuchadnezzar, who destroyed the earlier temple by fire because it was predominantly cedar wood and burned like a matchbox. The Romans used a lot of fire too, but they did not just destroy it with fire; they literally dismantled that temple rock by rock and stone by stone. Les notes there are legendary stories that some Roman soldiers had heard tons of gold was hidden between the building blocks of the temple, so in order to go after that gold, they took it down stone by stone.
