Commentaries:
Jamieson, Fausset, and Brown
And let him that is on the housetop not get down into the house, neither enter therein, to take any thing out of his house—that is, let him take the outside flight of steps from the roof to the ground; a graphic way of denoting the extreme urgency of the case, and the danger of being tempted, by the desire to save his property, to delay till escape should become impossible.
