Charles Ellicott Commentary Micah 4:1

"But in the latter days it shall come to pass, that the mountain of Jehovah`s house shall be established on the top of the mountains, and it shall be exalted above the hills; and peoples shall flow unto it." — Micah 4:1 (ASV)

But in the last days. — There is again a sudden transition. Just as the third chapter began with a startling denunciation, immediately following the predicted blessings of the restored kingdom, so after that chapter, which closed in deepest gloom, there now rises a vision of glorious light.

The first three verses are almost identical with Isaiah chapter 2, Micah 4:2–4; and it has been almost an open question which of the two prophets is the original author of these verses, or whether indeed they both adopted the words from an older prophecy current at the time. Dr. Pusey takes a very decided stance, saying, “It is now acknowledged, almost universally, that the great prophecy, three verses of which Isaiah prefixed to his second chapter, was originally delivered by Micah... No one now thinks Micah adopted that great prophecy from Isaiah” (Minor Prophets, p. 289). This last statement, however, is far too sweeping; all that can be correctly said is that the preponderance of opinion favors Micah being regarded as the original writer.

In the top of the mountains — i.e., the mountain of the Lord’s house shall be spiritually elevated above all else, visible and invisible, and it shall be established forever.
