Matthew 24:1-3

1 Jesus then left the Temple. As he walked away, his disciples pointed out how very impressive the Temple architecture was.

2 Jesus said, "You're not impressed by all this sheer size, are you? The truth of the matter is that there's not a stone in that building that is not going to end up in a pile of rubble."

3 Later as he was sitting on Mount Olives, his disciples approached and asked him, "Tell us, when are these things going to happen? What will be the sign of your coming, that the time's up?"
