Jesus us referring to Daniel's story about the persecutions under Antiochus..
15 When ye therefore shall see the abomination of desolation, spoken of by Daniel the prophet, stand in the holy place, (whoso readeth, let him understand 16 Then let them which be in Judaea flee into the mountains: 17 Let him which is on the housetop not come down to take any thing out of his house: 18 Neither let him which is in the field return back to take his clothes.
Do you know what the abomination of desolation is..What and who is that ?
Also Jesus Christ said in Matthew 24:1-2--
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"
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"
1--"And as he went out of the temple, one of his disciples saith unto him, Master, see what manner of stones and what buildings are here!"
2--"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"
You do know that this prophecy about the Temple buildings Jesus Christ given has not yet come to all of its fulfilment yet..you do know that right.
