And it shall come to pass in the last days, that the mountain of the LORD's house shall be established in the top of the mountains…
(vers. 2-4): — Isaiah, "rapt into future times," sees the throne of the Lord of Israel established in sovereignty over all the nations of the earth, and they becoming willing subjects to Him, and friendly citizens to each other. The nations attain to true liberty, for they come to submit themselves to the righteous laws and institutions, and to the wise and gracious word and direction of that King whose service is perfect freedom; and to true brotherhood, for they leave their old enmities and conflicts, and make the same Lord their Judge and Umpire and Reconciler. And all this, not by some newly invented device of the nations, some new result of their own civilisation, but by the carrying out of the old original purpose and plan of God, that His chosen people of the Jews should be the ministers of these good things, and that in them should all nations of the earth be blessed, — that "out of Zion should go forth the law, and the Word of Jehovah from Jerusalem." This is the vocation of the Hebrew people. This, says the prophet, is the key to all our duties as a nation, this is the master light to guide us to right action.
(Sir E. Strachey, Bart.)
