ציטירנדיקער פּירוש אויף ישעיהו 33:4

as the last of the figs Heb. כְּאָסְפֵּי. This is vowelized with a “chataf kamatz” because it is not a verb in the present tense, like:, יוֹשֵב, sits, and אוֹמֵר, says; rather, it is a gerund, as in (Isa. 33:4): “The gathering of (אֹסֶף) the locusts”; like the gathering of קַיִץ. These are the last figs, which are inferior. And so did Jonathan render: as the late figs of the summer.

they shall clatter Heb. יִשְׁתַּקְשְׁקוּן. Jonathan renders: The sound of the clattering of their weapons is heard. And that is from the expression (Joel 2:24) “And the vats shall roar (וְהֵשִׁיקוּ),” and (Isa. 33:4) “Like the roaring (כְּמַשַק) of the cisterns.” It is an expression of making a sound heard.

In the city they clatter Heb. יָשֹׁקּוּ. This is an expression of making a din. Cf. (Isa. 33:4) “like the roaring (כְּמַשַּׁק) of the cisterns”; (Prov. 28: 15) “A growling (שּׁוֹקֵק) bear”; (Zeph. 2:9) “the clattering of (מִמְשַׁק) the thorns.” Jonathan, however, renders it as an expression of arms (נֶשֶק). They are armed.

a rattling of nettles The sound made by the nettles growing there because there are no passersby, and they knock against each other and make sounds.
