Charles Ellicott Commentary Isaiah 29:7

"And the multitude of all the nations that fight against Ariel, even all that fight against her and her stronghold, and that distress her, shall be as a dream, a vision of the night." — Isaiah 29:7 (ASV)

Against her and her munition. —The word is a rare one, but probably stands here for the new fortifications by which Uzziah and Hezekiah had defended Jerusalem.
