On the other hand, re the words translated "congregation",
"To everything the is a season, and a time to every purpose under heaven."
You might say, there was a time to DE-congregate from the accustomed place of assembly for the "congregated throngs".:

“When you catch sight of the disgusting thing that causes desolation, as spoken of through Daniel the prophet, standing in a holy place, . . . then let those in Judea begin fleeing to the mountains.” (Matt. 24:15, 16) But how would Jesus’ followers recognize when this prophecy was being fulfilled?

14 As events unfolded, the meaning of Jesus’ words became clear. In 66 C.E., Roman armies under Cestius Gallus arrived in Jerusalem to quell a Jewish rebellion. When the Jewish rebels, known as the Zealots, sought refuge inside the temple fortress, Roman soldiers began to undermine the temple wall. For alert Christians, the meaning was plain to see: A pagan army with its idolatrous standards (“the disgusting thing”) got as far as the temple wall (“a holy place”). It was time for Jesus’ followers to “begin fleeing to the mountains.” But how would they get out of a city that was under siege? Events were about to take an unexpected turn.

15 For no apparent reason, Cestius Gallus and his troops withdrew from Jerusalem and began retreating. The Zealots gave chase. With the warring parties away, Jesus’ followers suddenly had an opportunity to flee. Jesus had specifically instructed them to leave their material possessions behind and depart without delay. (Read Matthew 24:17, 18.) Was prompt action really necessary? The answer soon became clear. Within days, the Zealots returned and began forcing the inhabitants of Jerusalem and Judea to join the rebellion. Conditions within the city rapidly deteriorated as rival Jewish factions struggled for control. Flight became increasingly difficult. When the Romans returned in 70 C.E., flight became impossible. (Luke 19:43) Any who had lingered were trapped! For the Christians who had fled to the mountains, heeding Jesus’ instructions meant saving their lives." [link to wol.jw.org]

This isn't preterism- saying it's all already happened, b/c also expecting a further fulfillment in the "great tribulation."
I hope someone can figure out 1.that, and if so, then 2.how this might apply to subject under discussion.

Right now I have to go see about someone just taken to hospital very ill.
