Mark 13:1-4

1 As Jesus was leaving the Temple, one of his followers said to him, "Look, Teacher! How beautiful the buildings are! How big the stones are!"

2 Jesus said, "Do you see all these great buildings? Not one stone will be left on another. Every stone will be thrown down to the ground."

3 Later, as Jesus was sitting on the Mount of Olives, opposite the Temple, he was alone with Peter, James, John, and Andrew. They asked Jesus,

4 "Tell us, when will these things happen? And what will be the sign that they are going to happen?"
