King James Version (KJV)
Woe to thee that spoilest, and thou {wast} not spoiled; and dealest treacherously, and they dealt not treacherously with thee! when thou shalt cease to spoil, thou shalt be spoiled; {and} when thou shalt make an end to deal treacherously, they shall deal treacherously with thee.
Modern English
Woe to you who destroy, but you weren’t destroyed; and who betray, but nobody betrayed you! When you have finished destroying, you will be destroyed; and when you have finished betrayal, you will be betrayed.
Hebrew
ה֣וֹי שׁוֹדֵ֗ד וְאַתָּה֙ לֹ֣א שָׁד֔וּד וּבוֹגֵ֖ד וְלֹא־בָ֣גְדוּ ב֑וֹ כַּהֲתִֽמְךָ֤ שׁוֹדֵד֙ תּוּשַּׁ֔ד כַּנְּלֹתְךָ֥ לִבְגֹּ֖ד יִבְגְּדוּ־בָֽךְ׃
