Then let them who are in Judea flee into the mountains:
All Commentaries on Matthew 24:16 Go To Matthew 24
John Chrysostom
AD 407
Having spoken of the ills that were to overtake the city, and of the trials of the apostles, and that they should remain unsubdued, and should overrun the whole world, He mentions again the Jews' calamities, showing that when the one should be glorious, having taught the whole world, the others should be in calamity.
And see how He relates the war, by the things that seem to be small setting forth how intolerable it was to be. For, Then, says He, let them which be in Judæa flee into the mountains. Then, When? When these things should be, when the abomination of desolation should stand in the holy place. Whence he seems to me to be speaking of the armies. Flee therefore then, says He, for thenceforth there is no hope of safety for you.
