Isa 42:15-16 | KD | STEP | The delivery takes place, and the whole world of nature undergoes a metamorphosis, which is subservient to the great work of the future. “I make waste mountains and hills, and all their herbage I dry up, and change streams into islands, and lakes I dry up.” Here is another example of Isaiah’s favourite palindromy, as Nitzsch calls this return to a word that has been used before, or linking on the close of a period of its commencement. Jehovah’s panting in labour is His almighty fiery breath, which turns mountains and hills into heaps of ruins, scorches up the vegetation, condenses streams into islands, and dries up the lakes; that is to say, turns the strange land, in which Israel has been held captive, into a desert, and at the same time removes all the hindrances to His people’s return, thus changing the present condition of the world into one of the very opposite kind, which displays His righteousness in wrath and love.

‏ Isaiah 42:15-16

The delivery takes place, and the whole world of nature undergoes a metamorphosis, which is subservient to the great work of the future. “I make waste mountains and hills, and all their herbage I dry up, and change streams into islands, and lakes I dry up.” Here is another example of Isaiah’s favourite palindromy, as Nitzsch calls this return to a word that has been used before, or linking on the close of a period of its commencement. Jehovah’s panting in labour is His almighty fiery breath, which turns mountains and hills into heaps of ruins, scorches up the vegetation, condenses streams into islands, and dries up the lakes; that is to say, turns the strange land, in which Israel has been held captive, into a desert, and at the same time removes all the hindrances to His people’s return, thus changing the present condition of the world into one of the very opposite kind, which displays His righteousness in wrath and love. Isa 42:16

The great thing which is brought to pass by means of this catastrophe is the redemption of His people. “And I lead the blind by a way that they know not; by steps that they know not, I make them walk: I turn dark space before them into light, and rugged places into a plain. These are the things that I carry out, and do not leave.” The “blind” are those who have been deprived of sight by their sin, and the consequent punishment. The unknown ways in which Jehovah leads them, are the ways of deliverance, which are known to Him alone, but which have now been made manifest in the fulness of time. The “dark space” (machshâk) is their existing state of hopeless misery; the “rugged places” (ma‛ăqasshı̄m) the hindrances that met them, and dangers that threatened them on all sides in the foreign land. The mercy of Jehovah adopts the blind, lights up the darkness, and clears every obstacle away. “These are the things” (haddebhârı̄m): this refers to the particulars already sketched out of the double manifestation of Jehovah in judgment and in mercy. The perfects of the attributive clause are perfects of certainty.
