John Gill Commentary Isaiah 10:33

"Behold, the Lord, Jehovah of hosts, will lop the boughs with terror: and the high of stature shall be hewn down, and the lofty shall be brought low." — Isaiah 10:33 (ASV)

Behold, the Lord, the Lord of hosts, shall lop the bough with terror Cut off the king of Assyria and his army, in a most terrible manner; "the glory" of it, as in (Isaiah 10:18) the word signifies that which is the ornament, the beauty and glory, of the tree. The Septuagint render it, "the glorious ones"; and the Arabic version, "the nobles", the generals, and principal officers of the army; the Targum is, "behold, the Lord of the world, the Lord of hosts, shall cast forth the slain in his camp, as grapes that are trod in a winepress."

And the high ones of stature [shall] be hewn down; the princes of Assyria, so boasted of as kings, (Isaiah 10:8) comparable to tall trees, to oaks and cedars:

and the haughty shall be humbled; who, like their monarch, boasted of their wisdom and strength, (Isaiah 10:12–14) but now both he and they will be brought very low.
