There shall be a day when they shall come unto thee, From Assyria even to the cities of Egypt, And from Egypt even to the River, And from sea to sea, and from mountain to mountain.
Rashi on Micah
It is a day, and he shall come up to you—The prophet says: That day that you deride, saying that it has been nullified and gone away - that day is guarded and preserved, and has not become nullified. The enemy shall come up to you to destroy you.
Rashi on Micah
and the fortified cities—I.e., and until the fortified cities. And Jonathan renders (as follows): the great dark mountains.
