לֹֽא־יָרֵ֥עוּ וְלֹֽא־יַשְׁחִ֖יתוּ בְּכָל־הַ֣ר קָדְשִׁ֑י כִּֽי־מָלְאָ֣ה הָאָ֗רֶץ דֵּעָה֙ אֶת־יְהוָ֔ה כַּמַּ֖יִם לַיָּ֥ם מְכַסִּֽים׃ (פ)
They shall not hurt nor destroy In all My holy mountain; For the earth shall be full of the knowledge of the LORD, As the waters cover the sea.
Ibn Ezra on Isaiah
They shall not hurt, etc. The asp and cockatrice will do no harm, as if all Palestine were full of the knowledge of the Lord; for it is an acknowledged fact, that he who knows the Lord will never destroy, but always build and improve.
Ibn Ezra on Isaiah
כמים אשר לים מכסים ═ כמים לים מכסים Knowledge will increase, like the water which covers the sea. The water is never stopped, so knowledge will continually make progress.
