Charles Ellicott Commentary Nahum 3:13

"Behold, thy people in the midst of thee are women; the gates of thy land are set wide open unto thine enemies: the fire hath devoured thy bars." — Nahum 3:13 (ASV)

Your people ... are women, not in their notoriously effeminate and luxurious habits (see Layard, p. 360), but with reference to their panic-stricken condition at the time of the catastrophe. They are fearful as women (Jeremiah 51:30), because they find avenues laid open to the enemy, and the remaining defences consuming in the flames.
