Matthew 24:1-2

24:1 And Jesus went out, and departed from the temple: and his disciples came to [him] for to shew him the buildings of the temple. 24:2 And Jesus said unto them, See ye not all these things? verily I say unto you, There shall not be left here one stone upon another, that shall not be thrown down.

Luke 21:5-7

21:5 And as some spake of the temple, how it was adorned with goodly stones and gifts, he said, 21:6 [As for] these things which ye behold, the days will come, in the which there shall not be left one stone upon another, that shall not be thrown down. 21:7 And they asked him, saying, Master, but when shall these things be? and what sign [will there be] when these things shall come to pass?
