Gospel of Matthew Chapter 24 Vs. 17

 The Abomination of Desolation

Matthew 24:17 “Let him which is on the housetop not come down to take any thing out of his house:”

Let him which... Let Israel flee from Judea without taking time for valuables, lest they be overtaken by Antichrist’s.

on the house-top... The roofs of the houses in Eastern countries were made flat, so that they were favorable places for walking and retirement. The meaning here is, that he who should be on the housetop when this calamity came upon the city should flee without delay; He should not even take time to secure any article of apparel from his house. So sudden would be the calamity, that by attempting to do this He would endanger his life.

Him which is on the house-top (ὁ ἐπὶ τοῦ δώματος)

From roof to roof there might be a regular communication, called by the Rabbis the road of the roofs. Thus a person could make his escape passing from roof to roof, till, at the last house, he would descend the stairs on the outside of the house, but within the exterior court. The urgency of the flight is enhanced by the fact that the stairs lead into this court. Though you must pass by the very door of your room, do not enter to take anything out. Escape for your life.

When that event occurs, those… in Judea should flee to the mountains. They should not be concerned about taking anything with them.
