(2) It shall come to pass in the last days.--The three verses that follow are found in almost identical form in Micah 4:1-3, with the addition of a verse (Micah 4:4) which describes the prosperity of Judah--every man sitting "under his vine and his fig-tree," as in the days of Solomon. Whether (1) Isaiah borrowed from Micah, or (2) Micah from Isaiah, or (3) both from some earlier prophet, or (4) whether each received an independent yet identical revelation, is a problem which we have no adequate data for solving. Micah prophesied, like Isaiah, under Ahaz, Jotham, and Hezekiah, and so either may have heard it from the other. On the other hand, the prophecy of the destruction of Jerusalem, on which these verses follow, in Micah 3:12, appears from Jeremiah 26:18 to have been spoken in the days of Hezekiah. On the whole, (3) seems to have most to commend it. (See Introduction.)

For "in the last days" read latter or after days; the idea of the Hebrew words, as in Genesis 49:1; Numbers 24:14, being that of remoteness rather than finality. For the most part (Deuteronomy 4:30; Deuteronomy 31:29) they point to the distant future of the true King, to the time of the Messiah.

The mountain of the Lord's house.--The prophet's vision of the far-off days sees, as it were, a transfigured and glorified Jerusalem. Zion, with the Temple, was to be no longer surrounded by hills as high as, or higher than, itself (Psalm 125:2), scorned by other mountains (Psalm 68:16-17); but was to be to Israel as a Sinai or a Lebanon, as a Mount Meru, or an Olympus, "an exceeding high mountain" (Ezekiel 40:2), whose physical elevation should answer to its spiritual. (Comp. Zechariah 14:10.) So in that vision of the future, the waters of Shiloah, that went softly, were to become a broad and rushing river (Isaiah 33:21; Ezekiel 47:3-12). So, when men had been taught by experience that this ideal was to be realised in no Jerusalem or earth, the seer of Patmos saw a yet more transcendent vision of the glories of the heavenly Jerusalem (Revelation 21:10 to Revelation 22:5), and yet even these were but types and figures of divine and ineffable realities.

All nations shall flow unto it.--Better, all the nations--i.e., the heathen as distinct from Israel. The prophet sees and welcomes the approach of pilgrims from all regions of the earth to the new sanctuary. Thus early in his work was Isaiah (half unconsciously as to the manner in which his vision was to be realised) the prophet of a universal religion, of which the truths of Judaism were the centre, and of a catholic Church. In the admission of proselytes, commemorated in Psalms 87 (probably written about this time), we may see what may either have suggested the prophecy, or have seemed as the first-fruits of its fulfilment.

Verses 2-4. - PROPHECY OF THE LAST DAYS. The resemblance of this prophecy to Micah 4:1-3 is so close as to necessitate the conclusion either that one of the two prophets copied from the other, or that both copied from an earlier document. The latter view, which is that taken by Rosenmüller, Maurer, De Wette, Meier, and Mr. Cheyne, seems preferable. Verse 2. - In the last days; literally, in the sequel of the days; but generally used of a remote future (Genesis 49:1; Numbers 24:14; Deuteronomy 4:30, etc.). The mountain of the Lord's house; i.e. the Church, the true Zion, which is to be the antitype of the existing Zion, and is therefore given its material attributes. Spiritually, it would be a "mountain," as "a city set on a hill," which "could not be hid" (Matthew 5:14); and again, as occupying a position from which it would command the whole earth. In the top of the mountains; rather, at the head of the mountains; i.e. with pre-eminence over them. The metaphor is drawn from the common physical fact of a high mountain range culminating in a single supreme eminence. So Mount Hermon towers above the rest of the Antilibanus, Demavend over Elburz, Rowandiz over Zagros. The "mountains" above which the true Zion shall tower are the kingdoms, or perhaps the religions, of the earth. All nations; literally, all the nations; i.e. "all the nations of the earth" (comp. Psalm 72:11). Shall flow; or, stream. A constant accession of converts from all quarters is intended. These are represented as continually streaming upward into the holy mountain of God's house.

2:1-9 The calling of the Gentiles, the spread of the gospel, and that far more extensive preaching of it yet to come, are foretold. Let Christians strengthen one another, and support one another. It is God who teaches his people, by his word and Spirit. Christ promotes peace, as well as holiness. If all men were real Christians, there could be no war; but nothing answering to these expressions has yet taken place on the earth. Whatever others do, let us walk in the light of this peace. Let us remember that when true religion flourishes, men delight in going up to the house of the Lord, and in urging others to accompany them. Those are in danger who please themselves with strangers to God; for we soon learn to follow the ways of persons whose company we keep. It is not having silver and gold, horses and chariots, that displeases God, but depending upon them, as if we could not be safe, and easy, and happy without them, and could not but be so with them. Sin is a disgrace to the poorest and the lowest. And though lands called Christian are not full of idols, in the literal sense, are they not full of idolized riches? and are not men so busy about their gains and indulgences, that the Lord, his truths, and precepts, are forgotten or despised?And it shall come to pass in the last days,.... The days of the Messiah, as Aben Ezra rightly interprets it; and it is a rule laid down by Kimchi and Ben Melech, that wherever the last days are mentioned, the days of the Messiah are intended. The days of the Messiah commenced in the latter part of the Old Testament dispensation, or Jewish world, towards the close of their civil and church state, at the end of which he was to come, Habakkuk 2:3 and accordingly did, which is called the end of the world, and the last days; that is, of that state, Hebrews 1:2 and ushered in the world to come, or Gospel dispensation, which is properly the days of the Messiah, reaching from his first to his second coming; the first of which were the times of John the Baptist, Christ and his apostles; the latter days of that dispensation take in the rise and reign of antichrist, 1 Timothy 4:1 the last days of it are those which bring in the perilous times, the spiritual reign of Christ, and the destruction of antichrist, and which will precede the personal coming of Christ, 2 Timothy 3:1 and these are the days here referred to.

That the mountain of the Lord's house shall be established in the top of the mountains; by "the mountain" of the Lord's house is meant, not Mount Moriah, on which the temple was built, as Kimchi interprets it; nor the temple itself, as the Targum; though in the last days of it, and at the first coming of the Messiah, that had a greater glory than ever it had before, through the personal presence of Christ in it; through the effusion of the Holy Spirit upon the apostles there, on the day of Pentecost; and through the Gospel being first preached here by Christ and his apostles, from whence it went forth into all the world, as is afterwards predicted it should; but the kingdom of Christ, which is his church, is here designed; called "the Lord's house", because of his building, and where he dwells, and which he will at this time beautify and glorify; the materials of it are lively stones, or true believers; laid on Christ the foundation, into which there is no right entrance but through faith in him, who is the door, and where is plenty of provisions; the pillars and beams of it are the ministers of the Gospel, and its windows are the ordinances: here Christ is as a Son over his own house; he is the Master of it, the High Priest and Prophet in it; and his servants are the stewards of it, to give to everyone their portion; and happy are they that have a name and a place in it: and it is called "the mountain", in allusion to Mount Zion, on which the temple stood; because of its immovableness, being secured in the everlasting and electing love of God, and in the unalterable covenant of grace, founded on the Rock Christ, and guarded by the mighty power of God. This is "established in the top of the mountains"; in Christ, who is higher than the kings of the earth, signified by mountains, Revelation 17:9 who is the Head of all principality and power; not in their first head, or in themselves, is the establishment of the saints, but in Christ, 2 Corinthians 1:21 he is the stability of their persons, of their grace, and of their life, spiritual and eternal. Here it seems to denote the superiority of the kingdom and interest of Christ to all civil and religious states; the settlement and security of it; its standing above them, and continuance when they shall be no more, even all antichristian states, both Papal, Pagan, and Mahometan, Revelation 16:19.

and shall be exalted above the hills; Mount Zion is above Mount Sinai, or the Gospel dispensation is preferable to the legal one. It is an observation of Jarchi, that it shall be exalted by a greater sign or miracle that shall be done in it than was done in Sinai, Carmel, and Tabor; the law was given on Sinai, and many wonders wrought; but on Zion the Messiah himself appeared, and his Gospel was published, and miracles wrought by him. And in the latter day, when Christ, and he alone, shall be exalted, as he will at the time this prophecy refers to, Isaiah 2:11 the church will be exalted; the glory of the Lord will be risen upon her; the interest of Christ will exceed all other interests; his religion will be the prevailing one; the kingdoms of this world will become his; and his dominion will be from sea to sea, and from the rivers to the end of the earth. This may also denote the visibility of the kingdom and church of Christ; it will be as a city on a hill; and however obscure the church is now, being in the wilderness, it will at this time be visible to all:

and all nations shall flow unto it; that is, many out of all nations shall be converted, and come freely and willingly to join themselves to the church of Christ; they shall come in great numbers, in company together, and that continually, like flowing streams; they shall first flow to the Lord, and to his goodness, and then to his church and ordinances; see Isaiah 60:4.
