Mark 13:1-4

ASV(i) 1 And as he went forth out of the temple, one of his disciples saith unto him, Teacher, behold, what manner of stones and what manner of buildings! 2 And Jesus said unto him, Seest thou these great buildings? there shall not be left here one stone upon another, which shall not be thrown down.
3 And as he sat on the mount of Olives over against the temple, Peter and James and John and Andrew asked him privately, 4 Tell us, when shall these things be? and what [shall be] the sign when these things are all about to be accomplished?
