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

“Then to shew how inevitable the evils that should come upon the Jews, and how infinite their calamity, He adds, And let him which is on the housetop, not come down to take any thing out of his house, for it was better to be saved, and to lose his clothes, than to put on a garment and perish; and of him who is in the field He says the same. For if those who are in the city fly from it, little need is there for those who are abroad to return to the city. But it is easy to despise money, and not hard to provide other raiment; but how can one avoid natural circumstances? How can a woman with child be made active for flight, or how can she that gives suck desert the child she has brought forth? Woe, therefore, to them that are with child, and to them that give suck in those days; to the one, because they are encumbered, and cannot easily fly, bearing about the burden of the womb; to the other, because they are held by compassion for their children, and cannot save with them those whom they are suckling.”
