תַּ֤חַת בָּשְׁתְּכֶם֙ מִשְׁנֶ֔ה וּכְלִמָּ֖ה יָרֹ֣נּוּ חֶלְקָ֑ם לָכֵ֤ן בְּאַרְצָם֙ מִשְׁנֶ֣ה יִירָ֔שׁוּ שִׂמְחַ֥ת עוֹלָ֖ם תִּֽהְיֶ֥ה לָהֶֽם׃
En lugar de vuestra doble confusión, y de vuestra deshonra, os alabarán en sus heredades; por lo cual en sus tierras poseerán doblado, y tendrán perpetuo gozo.
Rashi on Isaiah
Instead of your shame which was twofold, even they would constantly bemoan their disgrace as their lot. That is to say that instead of until now My people were constantly bemoaning disgrace, their lot... There are instances of רִנָּה that is an expression of mourning. Comp. (Lam. 2:19) “Rise, cry (רֹנִּי) at night,” and comp. (I Kings 22:36) “A cry (הָרִנָּה) passed through the camp,” concerning Ahab’s death.
Ibn Ezra on Isaiah
משנה Double. The verb you shall inherit is to be supplied.
