Luke 21:6

“As for these things which you behold, the days will come, in which there will not be left here one stone upon another, that will not be thrown down.”

And so He informed them that days were coming when the temple would be torn down, with not one stone to be left on another, just as it had been in the days of Jeremiah among the rubble of the houses (2 Chronicles 36:19; Jeremiah 7:12; Lamentations 4:1). God would repeat His judgments upon it as He had promised in the book of Daniel would happen once the Messiah had been cut off (Daniel 9:26). Interestingly there is little in these words of Jesus from Luke 21:8 which has not already been clearly depicted by the prophets in the Old Testament as coming on the world in the future. His genius lies in bringing it all together.
