Luke 21:20 And when ye shall see Jerusalem compassed with armies, then know that the desolation thereof is nigh.
When Jesus says "ye shall see Jerusalem compassed with armies" (Luke 21:20), he's referring to the first part of Daniel 11:31: "And arms shall stand on his part". And when Jesus says "the desolation" in Luke 21:20, he's referring to the "abomination of desolation" part of Daniel 11:31, just as in Matthew 24:15, he's referring to the "abomination of desolation" part of Daniel 11:31.
So Luke 21:20-23 isn't referring to 70 AD, nor to the pillaging of Jerusalem which will occur at the very end of the future tribulation, right before Jesus' 2nd coming to save Jerusalem (Zechariah 14), but is referring to what will happen mid-tribulation, when the Antichrist will antitypically fulfill Daniel 11:31 at the start of his future, literal 3.5-year worldwide reign (Revelation 13:4-18), during which 3.5 years, Jerusalem will be trodden down by the Gentiles (Revelation 11:2b), which future treading down is what Luke 21:24 is referring to.
Regarding the "abomination of desolation", Daniel 11:31 was typically fulfilled by the abomination of desolation in 1 Maccabees 1:54, which occurred in the holy place (the inner sanctum) of the 2nd Jewish temple in Jerusalem in the time of Antiochus IV. But per Jesus' statement in Matthew 24:15, the church will see the abomination of desolation in Daniel 11:31 fulfilled (antitypically) in the future, when the church will see the abomination of desolation "stand" "in" the holy place (of a 3rd Jewish temple in Jerusalem). This future abomination of desolation could be a standing, android image of the Antichrist (Revelation 13:15) which his followers ("they") will put in the holy place of the temple (Daniel 11:31) to be worshipped (Revelation 13:15), after "they" have stopped the daily Mosaic animal sacrifices which the ultra-Orthodox Jews will have restarted in front of the temple (Daniel 11:31). This image will "pollute" the holy place of the temple (Daniel 11:31).
The Antichrist will then fulfill Daniel 11:36 and 2 Thessalonians 2:4 by sitting himself (at least one time) in the temple and proclaiming himself God. By the power of Satan (the dragon, Revelation 12:9), the Antichrist (the individual-man aspect of the beast) will then rule and be worshipped by all the nations of the earth for 3.5 literal years (Revelation 13:4-18), and will physically overcome Biblical Christians in every nation (Revelation 13:7-10, Revelation 14:12-13, Revelation 20:4-6, Matthew 24:9-13).
Also, from the day on which (antitypically) "the daily sacrifice shall be taken away, and the abomination that maketh desolate set up, there shall be 1,290 days. Blessed is he that waiteth, and cometh to the 1,335 days" (Daniel 12:11-12, Revelation 16:15). Also, because the Antichrist will fulfill Daniel 11:31 antitypically and will fulfill Daniel 11:36 for the first (and only) time, then he will also fulfill all of Daniel 11:21-45 (the first part of it antitypically, and the rest for the first and only time) when he arises on the world stage, for that passage refers to the career of the same man. And since the Antichrist will fulfill all of Daniel 11:21-45 when he arises on the world stage, then just preceding his arising on the world stage, Daniel 11:13-19 could be fulfilled antitypically by an Iraqi Baathist General completely defeating and occupying Israel and Egypt with a huge Iraqi Army (Daniel 11:15-17; in verse 17 the original Hebrew word translated as "daughter" is "bath").

Luke 21:21 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.
Regarding "Judaea" (Luke 21:21, Matthew 24:16), note that this doesn't have to mean first century Judaea. For there are many churches in Judaea (southern Israel) still today. They contain mostly Gentile believers, not just Jewish believers. The church began and has always been in Judaea: "Then had the churches rest throughout all Judaea" (Acts 9:31); "the churches of Judaea" (Galatians 1:22); "the churches... in Judaea" (1 Thessalonians 2:14). Matthew 24:16 refers to those in the church, both Gentiles and Jews, who will be living in Judaea at the future point in time when the abomination of desolation (possibly a standing, android image of the Antichrist) is set up in the holy place (the inner sanctum) of a 3rd Jewish temple in Jerusalem (Matthew 24:15, Daniel 11:31).
The Antichrist's persecution of the church could begin in Jerusalem and Judaea right after the abomination of desolation is set up and the Antichrist himself sits in the temple and proclaims himself God (2 Thessalonians 2:4, Daniel 11:36). So to avoid this persecution (cf. Matthew 10:23a), those in the church living in Judaea should flee immediately after they see the abomination of desolation set up (Matthew 24:15-16), which event could occur at the midpoint of the future tribulation of Revelation chapters 6 to 18 and Matthew 24, and which event could mark the start of the Antichrist's future, literal 3.5-year worldwide reign (Revelation 13:4-18). Eventually, the Antichrist's persecution of the church will reach every nation of the earth (Revelation 13:7-10, Revelation 14:12-13, Revelation 20:4-6, Matthew 24:9-13), so that the basic principle of Matthew 24:16 of fleeing (the Antichrist's persecution) would apply to believers around the world.
Just as the woman in Revelation 12:6 represents many different people in the church around the world, so the protected wilderness place she flees to represents many different protected wilderness places around the world. When those in the church living in Judaea see the abomination of desolation set up, they should flee into places in the wilderness east of Judaea, the mountains (Matthew 24:16) of Jordan. And those in the church who will be living in places in the world other than Judaea should flee into other wilderness places, mountainous places (Ezekiel 7:16), in the regions of the world where they live.
And they should have prepared beforehand hideouts in these wilderness/mountain places, hideouts already fully stocked with all of the emergency supplies of food, water, warm clothing, etc., that they and their families and fellow Christians will need to survive (1 Timothy 5:8, Matthew 24:45-46, cf. Genesis 41:48,36, Genesis 45:7) until Jesus returns, possibly on the 1,335th day after the abomination of desolation is set up (Daniel 12:11-12, Revelation 16:15). For they shouldn't carry any supplies with them when they flee (Matthew 24:17-18). They should flee as unhindered and quickly as possible, knowing that when the abomination of desolation is set up, that could signal the beginning of the Antichrist's future, literal 3.5-year Luciferian (Satanic) worldwide reign of terror (Revelation 13:4-18, Revelation 12:9), when he will be given power to make war against all those in the church that he can get his hands on, and to physically overcome them and kill them (by beheading) in every nation (Revelation 13:7-10, Revelation 14:12-13, Revelation 20:4-6, Matthew 24:9-13).

Luke 21:24 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.
The treading down of Jerusalem during the "times" (Greek: kairos, G2540) of the Gentiles in Luke 21:24 can refer to what will occur during certain years in our future, the same "times" (kairos, G2540), or years, referred to in Revelation 12:14b, during which the Gentiles will tread down Jerusalem as part of the Antichrist's future, literal 3.5-year worldwide reign (Revelation 11:2b, Revelation 13:5-18), during the 2nd half of the future tribulation of Revelation chapters 6 to 18 and Matthew 24.
Similarly, when Paul says "until the fulness of the Gentiles be come in" (Romans 11:25), he means until a full number of genetic Gentile individuals have become saved, which won't happen until near the end of the tribulation, right before Jesus' 2nd coming (Romans 11:26).
Immediately after the tribulation, at Jesus' 2nd coming (Matthew 24:29-30), all the unsaved elect genetic Jews will become saved (Romans 11:26-28) by God's grace when they see the returned Jesus in person and believe in him (Zechariah 12:10-14). And so they will all become part of the church at that time, just as when genetic Jews believe in Jesus now they become part of the church, for there are now no believers outside of the church (Ephesians 4:4-6).
And the genetic Jews who will become believers at the 2nd coming will all become part of the church by receiving some measure of the Holy Spirit, who is "the spirit of grace and of supplications" in Zechariah 12:10 (Hebrews 10:29c, Romans 8:26), just as genetic Jewish believers today become part of the church by receiving some measure of the Holy Spirit. For it's by receiving some measure of the Holy Spirit that both genetic Jewish believers and genetic Gentile believers become part of the church (1 Corinthians 12:13).
