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.
