אֲשֶׁ֤ר חָשְׁב֣וּ רָע֣וֹת בְּלֵ֑ב כָּל־י֝֗וֹם יָג֥וּרוּ מִלְחָמֽוֹת׃
qui conçoivent de mauvais desseins dans leur cœur, chaque jour fomentent des guerres.

He equated him with a lion which is the strongest of the animals; and compared him to a young lion, regarding his lightness and alacrity [being] beyond the adult lion. That is why he used two nouns, as "cub" alone is also said about other animals when they are small; as it is stated (Lamentations 4:3), "Even jackals offer the breast, and suckle their cubs." And the intention here is cub of the lion species, and it is a construct phrase. And so did Yonatan ben Uzziel translate, "I compare you, Judah, to a cub that is the child of lions." But to me, it appears that gur is an expression of provoking, [like] the expression, "every day, they provoke (yaguru) wars" (Psalms 140:3); [and] "begin to inherit, and provoke (hitgar) war against it" (Deuteronomy 2:24). And the explanation of "gur lion" is a lion that is provoked, as he is at his most dangerous then.
