Matthew 24:1-3

And Jesus went out from the temple, and was going on his way; and his disciples came to him to show him the buildings of the temple. But he answered and said unto them, See ye not all these things? verily I say unto you, There shall not be left here one stone upon another, that shall not be thrown down. And as he sat on the mount of Olives, the disciples came unto him privately, saying, Tell us, when shall these things be? and what shall be the sign of thy coming, and of the end of the world?
