In that day, he which shall be upon the housetop
Either for diversion or devotion, when he shall hear that the Roman armies are approaching to Jerusalem, to besiege it:
and his stuff in the house;
or "his vessels", his goods and furniture; or his utensils, and instruments of trade and business:
let him not come down;
the inner way of the house, from the top:
to take it away;
with him in his flight, but let him descend by the steps, or ladder, on the outside of the house, and make his escape directly to Pella, or the mountains:
and he that is in the field;
at work, and has laid down his clothes in some certain part of the field, or at home:
let him likewise not return back;
to fetch them, but make the best of his way as he is; (See Gill on Matthew 24:17) and (See Gill on Matthew 24:18).
