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

24:17 Let not him that is on the house top come down to take any thing out of his house - It may be remembered that their stairs used to be on the outside of their houses.
Mt 24:17 Let him which is on the housetop. The flat roofs were sleeping places. All must be done without a moment's delay.
