Except I don't take Luke 21:23 to be meaning the great trib recorded in Matthew 24:21. According to Daniel 12, a resurrection of the dead follows the great tribulation recorded in Matthew 24:21. No resurrection of the dead followed what happened in 70 AD nor does Luke 21 ever use the Greek word thlipsis to describe any of those things.
According to my Strong's thlipsis is not found anywhere in Luke 21.
David, you agree that Luke 21:20-24 is part of the Olivet Discourse, right? But, you disagree that it's a record of the same event as recorded in Matthew 24:15-22 and Mark 13:14-20.
Can you tell me when you think Jesus said what is recorded in Luke 21:20-24 in relation to what He said in Matthew 24:15-22? Which of those do you think He said first? How long after that do you think He said what is recorded in the other passage?
Here are the passages in question (I'm trying to keep it simple here by not including Mark 13:14-20 which is very similar to Matthew 24:15-22):
Matthew 24:15
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. 19
And woe unto them that are with child, and to them that give suck in those days! 20 But pray ye that your flight be not in the winter, neither on the sabbath day
: 21
For then shall be great tribulation, such as was not since the beginning of the world to this time, no, nor ever shall be. 22 And except those days should be shortened, there should no flesh be saved: but for the elect's sake those days shall be shortened.
Luke 21:20 And
when ye shall see Jerusalem compassed with armies, then know that the
desolation thereof is nigh. 21
Then let them which are in Judaea flee to the mountains; and let them which are in the midst of it depart out; and let not them that are in the countries enter thereinto. 22 For these be the days of vengeance, that all things which are written may be fulfilled. 23
But woe unto them that are with child, and to them that give suck, in those days! for there shall be great distress in the land, and wrath upon this people. 24 And they shall fall by the edge of the sword, and shall be led away captive into all nations: and Jerusalem shall be trodden down of the Gentiles, until the times of the Gentiles be fulfilled.
In each passage I bolded and color coded the parts that are the same or similar in each passage. You believe that Jesus said those things twice during the Olivet Discourse, such as "Then let them which are in Judea flee to the mountains", "woe unto them that are with child, and to them that give suck in those days!" and there "shall be great distress/tribulation". Don't you think that would've been confusing to those He was speaking to at the time? Wouldn't they have thought "Wait, didn't you already tell us about this?" the second time He said those in Judea should flee to the mountains and the second time He said "woe unto them that are with child, and to them that give suck in those days"? What is your explanation for this?
