Mark 13:2-6

And Jesus answering said unto him, Seest thou these great buildings? there shall not be left one stone upon another, that shall not be thrown down.

And as he sat upon the mount of Olives over against the temple, Peter and James and John and Andrew asked him privately,

Tell us, when shall these things be? and what shall be the sign when all these things shall be fulfilled?

And Jesus answering them began to say, Take heed lest any man deceive you:

For many shall come in my name, saying, I am Christ; and shall deceive many.
