Matt 24:15So when you see standing in the holy place ‘the abomination of desolation,’ described by the prophet Daniel (let the reader understand), 16
then let those in Judea flee to the mountains. 17Let no one on the housetop come down to retrieve anything from his house.
Luke 21:
20But when you see Jerusalem surrounded by armies, you will know that her desolation is near.
21Then let those who are in Judea flee to the mountains, let those in the city get out, and let those in the country stay out of the city.
22For these are the days of vengeance,
to fulfill all that is written.
23How miserable those days will be for pregnant and nursing mothers. For there will be great distress upon the land and wrath against this people.
24They will fall by the edge of the sword and be led captive into all the nations. And Jerusalem will be trodden down by the Gentiles,
until the times of the Gentiles are fulfilled.
Luke 17:
20When asked by the Pharisees when the kingdom of God would come, Jesus replied, “The kingdom of God will not come with observable signs.
21Nor will people say, ‘Look, here it is,’ or ‘There it is.’ For you see, the kingdom of God is in your midst.”

26Just as it was in the days of Noah, so also will it be in the days of the Son of Man:
27People were eating and drinking, marrying and being given in marriage, up to the day Noah entered the ark. Then the flood came and destroyed them all.
28It was the same in the days of Lot: People were eating and drinking, buying and selling, planting and building.
29But on the day Lot left Sodom, fire and brimstone rained down from heaven and destroyed them all.
30It will be just like that on the day the Son of Man is revealed.
31On that day, let no one on the housetop come down to retrieve his possessions. Likewise, let no one in the field return for anything he has left behind.32Remember Lot’s wife!
33Whoever tries to save his life will lose it, but whoever loses his life will preserve it.
34I tell you, on that night two people will be in one bed:
One will be taken and the other left. 35Two women will be grinding grain together: One will be taken and the other left.”
Psalm 11:1
For the choirmaster. Of David. In the LORD I take refuge. So how can you say to me, “Flee to your mountain like a bird! 2For behold, the wicked bend their bows; they set their arrow on the string to shoot from the shadows at the upright in heart.
All these verses are talking about the same thing. Fleeing to the mountain has a spiritual meaning rather than a physical one.
In the 70AD, those that ran to the mountains were rounded up and killed, IMO.
