The valley — A valley, so called from the multitude of Sennacherib's army slain there. Of the ashes — So called from the ashes of the sacrifices carried thither. Holy — All these places shall be parts of the holy city, and God's name shall be sanctified, and he shall be worshipped in them all. For ever — If we interpret the word for ever of a perpetuity, the church of God must here be understood, against which the gates of hell shall never prevail.
