אֲרִי־נֹ֭הֵם וְדֹ֣ב שׁוֹקֵ֑ק מֹשֵׁ֥ל רָ֝שָׁ֗ע עַ֣ל עַם־דָּֽל׃
Jako lew ryczący i niedźwiedź łaknący jest władca niegodziwy nad ludem ubogim.
Radak
משק, the root of the word is שקק, is grammatically parallel to such words as מכס, whose root is כסס, the meaning of the word is מן השוק, i.e. someone who comes and goes, not someone whose roots are in my house. The root occurs in that sense in Proverbs 28,15 דוב שוקק, “a prowling bear.” Both the roots כסס and שקק describe similar activities.
Rashi
like the roaring of the cisterns Like the sound of the roar of water gathering and falling into the cisterns in the river, so will those coming to plunder and pillage, roar. מַשַּׁק is an expression of roaring. Comp. (Prov. 28:15) “A roaring lion and a growling (שׁוֹקֵק) bear.” Also (Zeph. 2:9), “The noise (מִמְשַׁק) of the thorns.” When the wind blows on the thorns, and they knock against one another, they produce a sound. Comp. also, (Joel 2:9) “In the city they roar (יָשֹׁקּוּ).”
Rashi
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.
