אֶפְגְּשֵׁם֙ כְּדֹ֣ב שַׁכּ֔וּל וְאֶקְרַ֖ע סְג֣וֹר לִבָּ֑ם וְאֹכְלֵ֥ם שָׁם֙ כְּלָבִ֔יא חַיַּ֥ת הַשָּׂדֶ֖ה תְּבַקְּעֵֽם׃
내가 새끼 잃은 곰 같이 저희를 만나 그 염통 꺼풀을 찢고 거기서 암사자 같이 저희를 삼키리라 들짐승이 저희를 찢으리라
Rashi on Hosea
as a bereaving bear Heb. שַׁכּוּל. Like שּׁוֹכֵל, as you say חָנּוּן, gracious, and רַחוּם, merciful, so שַּׁכּוּל, i.e., entirely attired with bereavements and ready to bereave people.
Rashi on Hosea
and I will rend the enclosure of their heart like the habit of the bear, which holds its nails on the chest and rends until the heart. Another explanation: the enclosure of the heart Their heart which is closed from understanding to return to Me.
