ה֣וֹי שׁוֹדֵ֗ד וְאַתָּה֙ לֹ֣א שָׁד֔וּד וּבוֹגֵ֖ד וְלֹא־בָ֣גְדוּ ב֑וֹ כַּהֲתִֽמְךָ֤ שׁוֹדֵד֙ תּוּשַּׁ֔ד כַּנְּלֹתְךָ֥ לִבְגֹּ֖ד יִבְגְּדוּ־בָֽךְ׃ (ס)
Woe to thee that spoilest, and thou wast not spoiled; And dealest treacherously, and they dealt not treacherously with thee! When thou hast ceased to spoil, thou shalt be spoiled; And when thou art weary with dealing treacherously, they shall deal treacherously with thee.
Rashi on Isaiah
Woe To the enemy, that you constantly spoil, but you are not spoiled, and you constantly deal treacherously, but no man deals treacherously with you or spoils you.
Ibn Ezra on Isaiah
הוי Ho!1See c. i., note 13. Interjection of calling. The prophet addresses Assyria.
Rashi on Isaiah
when you finish being a spoiler, when you finish your spoiling of those upon whom it was decreed to be spoiled by you, you shall be spoiled.
