Isaiah 42:15

15 I will level the mountains and hills and blight all their greenery. I will turn the rivers into dry land and will dry up all the pools.

Isaiah 42:15 Meaning and Commentary

Isaiah 42:15

I will make waste mountains and hills
Kingdoms, greater and lesser; kings and governors, as Jarchi interprets it; and so Kimchi understands it of the kings of the nations; by them are meant the emperors of Rome, and their governors under them, that set themselves against Christ and his Gospel, but were overcome by him; these mountains and hills became a plain before him: "every mountain and island were moved out of their places, and the kings of the earth, and the great men hid themselves in the dens, and in the rocks of the mountains, and called upon them to fall on them, and hide them from the wrath of the Lamb", ( Revelation 6:14-16 ) : and dry up all their herbs;
the common people, and common soldiers that were with them, and on their side; comparable, for smallness, weakness, and number, to the grass of the mountains and hills: and I will make the rivers islands, and dry up the pools;
extirpate all the remains of idolatry, rivers and fountains being sacred with the Heathens, as mountains and hills were places where sacrifices were offered to idols. Unless by it rather should be meant, that the Lord would remove all impediments out of the way of his people, or which were obstacles of their conversion; just as he dried up the waters of the Red sea and Jordan, to make way for the people of Israel; to which the allusion may be, and which agrees with the following words.

Isaiah 42:15 In-Context

13 The LORD will march forth like a mighty hero; he will come out like a warrior, full of fury. He will shout his battle cry and crush all his enemies.

14 He will say, “I have long been silent; yes, I have restrained myself. But now, like a woman in labor, I will cry and groan and pant.

15 I will level the mountains and hills and blight all their greenery. I will turn the rivers into dry land and will dry up all the pools.

16 I will lead blind Israel down a new path, guiding them along an unfamiliar way. I will brighten the darkness before them and smooth out the road ahead of them. Yes, I will indeed do these things; I will not forsake them.

17 But those who trust in idols, who say, ‘You are our gods,’ will be turned away in shame.
