1 tc The Hebrew text reads “with terrifying power,” or “with a crash.” מַעֲרָצָה (ma’aratsah, “terrifying power” or “crash”) occurs only here. Several have suggested an emendation to מַעֲצָד (ma’atsad, “ax”) parallel to “ax” in v. 34; see HALOT 615 s.v. מַעֲצָד and H. Wildberger, Isaiah, 1:448.
sn As in vv. 12 (see the note there) and 18, the Assyrians are compared to a tree/forest in vv. 33-34.
2 tn Heb “the exalted of the height.” This could refer to the highest branches (cf. TEV) or the tallest trees (cf. NIV, NRSV).
