As he was leaving the temple, one of his disciples said to him, "Look, Teacher! What massive stones! What magnificent buildings!"
"Do you see all these great buildings?" replied Jesus. "Not one stone here will be left on another; every one will be thrown down."1
As Jesus was sitting on the Mount of Olives2 opposite the temple, Peter, James, John3 and Andrew asked him privately,
"Tell us, when will these things happen? And what will be the sign that they are all about to be fulfilled?"
Jesus said to them: "Watch out that no one deceives you.4
Many will come in my name, claiming, 'I am he,' and will deceive many.
