Zion's sake — Zion and Jerusalem are both put for the church, Hebrews 12:22. My peace — These seem to be the words of the prophet strongly resolving, notwithstanding all difficulties, to solicit God for the church's happiness, and constantly excite to the belief of it by his preaching, though it were long before it came, for Isaiah lived near two hundred years before this was accomplished. Righteousness — With reference to the Babylonians, understand it of the righteousness of God, who hath promised his people deliverance, and he must be righteous, and so understand salvation before; or rather, the vindicating of his people's cause in the eyes of the nations by the ruin of the Babylonians; he will shew that his people have a righteous cause. Lamp — And to that purpose is set up where it may be seen continually, to signify how eminently conspicuous this prosperous estate of the church should be among the nations, and as it may particularly relate to revealing of Christ unto the world.
