עַל־זֹאת֙ אֶסְפְּדָ֣ה וְאֵילִ֔ילָה אֵילְכָ֥ה שילל [שׁוֹלָ֖ל] וְעָר֑וֹם אֶעֱשֶׂ֤ה מִסְפֵּד֙ כַּתַּנִּ֔ים וְאֵ֖בֶל כִּבְנ֥וֹת יַעֲנָֽה׃
C’est pour cela que je veux donner cours à mes plaintes, à mes lamentations, circuler pieds-nus et sans vêtements, poussant des hurlements lugubres comme les chacals et des cris plaintifs comme les autruches.
Da'at Zekenim
ובתהו ילל ישימון, “and in an empty howling waste, etc.” in that very region which harbors only jackals and ostriches, as we know from Micah 1,8 which are constantly lamenting, I provided all that could be wished for. An alternate interpretation for the expression: ימצאהו בארץ מדבר. In this area where one could not logically have expected to find anything worth while, Israel found a real treasure i.e. the Torah which the Lord gave them.
Rashi
is considered mad Heb. מִשְׁתּוֹלֵל, considered mad by the people. Comp. (Micah 1:8) “I will go as a mad man (שׁוֹלָל).” This is equivalent to שׁוֹגֵג, inadvertent, which the Targum renders: שָׁלוּ. Likewise (II Sam. 6:7), “For his error (הַשַּׁל).”
Ibn Ezra
משתולל According to some it means "mad;" comp. שולל "mad"13A. V., "stripped." (Mic. 1:8); אשתללו "they are mad" (Ps. 76::6); perhaps all these words are serived from שלל "to deprive of property;"14The meaning of משתולל accordingly is "maketh himself a prey (A. V.). משתולל is the participle Hitpael of שלל.
