1 Heb “Woe [to] the destroyer.” In this context “the destroyer” appears to refer collectively to the hostile nations (vv. 3–4). Assyria would probably have been primary in the minds of the prophet and his audience.
2 Heb “and the deceitful one”; , “O traitor”; “you treacherous one.” In the parallel structure הוֹי (hoy, “woe [to]”) does double duty.
3 The form in the Hebrew text appears to derive from an otherwise unattested verb נָלָה (nalah). The translation follows the Qumran scroll 1QIsaa in reading ככלתך, a Piel infinitival form from the verbal root כָּלָה (kalah), meaning “finish.”
