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.
