פּירוש אויף ישעיהו 32:11

to be troubled (רְגָזָה) to be troubled. (This is an infinitive despite the absence of the ‘lammed.’)

חרדו Tremble. Imperative masculine. Comp. תעירו ye stir (Song 2:7); תמצאו ye find (Ib. 5:8). It may be considered as an elliptical expression.¹⁴The use of the imperative plural masculine instead of the feminine is called by I. E. דרך קצרה ellipsis, since the feminine requires the addition of two letters נָה the masculine only וּ; but the use of the termination ־ִים instead of the feminine וֹת (next verse), is explained by supplying the word כׂל all, which is masculine singular in form, but plural in meaning.

to undress (פְּשֹׁטָה) to undress. (This too is an infinitive with the ‘lammed’ missing.)

and to bare (וְעֹרָה) An expression of ‘naked’ (עֶרְיָה) (Micah 1:11).

and to gird (וַחֲגוֹרָה) Therefore, the accent is before the last syllable, and so did Jonathan render: Undress and bare yourselves and gird on your loins. Since they will undress and bare themselves of their garments, they will not gird on their garments but on their loins.
