זְאֵ֨ב וְטָלֶ֜ה יִרְע֣וּ כְאֶחָ֗ד וְאַרְיֵה֙ כַּבָּקָ֣ר יֹֽאכַל־תֶּ֔בֶן וְנָחָ֖שׁ עָפָ֣ר לַחְמ֑וֹ לֹֽא־יָרֵ֧עוּ וְלֹֽא־יַשְׁחִ֛יתוּ בְּכָל־הַ֥ר קָדְשִׁ֖י אָמַ֥ר יְהוָֽה׃ (ס)
豺狼必與羊羔一同吃草，獅子必像牛一樣吃草稈，蛇必以塵土為食物。在我聖山的全境，牠們都不傷人，也不害物——這是永恆者說的。
Ibn Ezra
The wolf and the lamb shall feed together. This is a figurative expression for peace will be established. Many imagine this to be done in such a way, that God will deprive the wolf of its natural voracity, as indicated by the words, And the lion shall eat straw like the bullock.
Rashi
and a serpent Indeed, dust is his food, which is always available for him. And the Midrash Aggadah explains: And a lion, like cattle, shall eat straw. Since we find that Esau will fall into the hands of the sons of Joseph, as it is said (Obadiah 18): “The house of Esau shall become stubble, and the house of Joseph a flame etc.” But [that they should fall] into the hands of the remaining tribes, who were compared to beasts, we do not find. It is, therefore, stated: “And a lion, like cattle, shall eat straw.” Those tribes that were compared to a lion, such as Judah and Dan, like Joseph, who was compared to an ox, shall devour Esau who was compared to straw.
