John Chrysostom — as excerpted in the Catena Aurea on Matthew 24:15-22

“(Hom. lxxvi.) But because it had often happened to the Jews to be recovered in very desperate circumstances, as in the times of Sennacherib and Antiochus, that no man might look for any such event now, He gave command to His disciples to fly, saying, Then let them which are in Judæa flee to the mountains.”
