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…
Consider what that prediction meant in Isaiah's time. He lived within well-defined boundaries and limitations: the Jew was not a great man in the sense of including within his personal aspirations all classes, conditions, and estates of men; left to himself he could allow the Gentiles to die by thousands daily without shedding a tear upon their fallen bodies; he lived amongst his own people; it was enough for him that the Jews were happy, for the Gentiles were but dogs. Here is a new view of human nature, great enlargement of spiritual boundaries.
(J. Parker, D. D.)
Parallel VersesKJV: 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, and shall be exalted above the hills; and all nations shall flow unto it.
