Matt 24-5 Luke 21 Mark 13
Do we agree they are speaking of the same event?
Luke obviously records something different than Matthew.
The following verses look to me as if they refer to the destruction of Jerusalem in 70 AD.
20 "But when you see Jerusalem surrounded by armies, then know that its desolation is near. 21 Then let those who are in Judea flee to the mountains, let those who are in the midst of her depart, and let not those who are in the country enter her. 22 For these are the days of vengeance, that all things which are written may be fulfilled. 23 But woe to those who are pregnant and to those who are nursing babies in those days! For there will be great distress in the land and wrath upon this people. 24 And they will fall by the edge of the sword, and be led away captive into all nations. And Jerusalem will be trampled by Gentiles until the times of the Gentiles are fulfilled.
Luke 21:20-24
Mathew 24:15 is different
"Therefore when you
see the 'abomination of desolation,' spoken of by Daniel the prophet, standing in the holy place" (whoever reads, let him understand),
The key, as Jesus said is understanding Daniel the Prophets writings about this.
The disciples asked a question, that prompted this discourse.
1 Then Jesus went out and departed from the temple, and His disciples came up to show Him the buildings of the temple. 2 And Jesus said to them, "Do you not see all these things? Assuredly, I say to you, not one stone shall be left here upon another, that shall not be thrown down." 3 Now as He sat on the Mount of Olives, the disciples came to Him privately, saying,
"Tell us, when will these things be? And what will be the sign of Your coming, and of the end of the age?"
They likely thought that the destruction of the temple, meant
the end of the age. So The Lord is trying to answer their question, that is based on a false premise and teach us as well.
Notice Luke does not mention Daniel.
I am sorry if I seem like I am side-stepping a very simple question.
The best I can do is say, what Luke records about Jerusalem is different that what Matthew records.
