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.
My holy mountain - Zion, i:e., Jerusalem. The seat of government and of Messiah's throne is put for the whole earth (Jeremiah 3:17).
For the earth shall be full of the knowledge of the Lord, as the waters cover the sea. As the waters find their way into every cavern of its depths, so Christianity shall pervade every recess of the earth (Habakkuk 2:14). As Isaiah 11:1-5 describe the personal qualities of Messiah, and Isaiah 11:6-9 the regenerating effects of His coming on the animal creation, so Isaiah 11:10-16 the results of it in the restoration of His people the Jews, and the conversion through them of the Gentiles.
