4:2 And many nations shall come, and say, Come, and let us go up to the mountain of the LORD, and to the house of the God of Jacob; and he will {c} teach us of his ways, and we will walk in his paths: for the law shall go forth of Zion, and the word of the LORD from Jerusalem.
(c) He shows that there is no true Church, except where the people are taught by God's pure word.
4:2 Many nations - This was in part fulfilled when so many proselyted servants of several nations, in love to their Jewish masters, and more to the God of the Jews, came up with them from Jerusalem. Come - So the Jews, released from captivity, encouraged each other; which was a fulfilling of this prophecy in part; the conversion of the multitude of the Gentiles to Christ, was a more eminent fulfilling of it. To the mountain - To the temple at Jerusalem, a type of Christ and the gospel church. From Jerusalem - In Jerusalem is declared the only way of worshipping God, and from thence the only law of right worship shall go forth, when the Messiah is come.
4:1-8 The nations have not yet so submitted to the Prince of Peace, as to beat their swords into ploughshares, nor has war ceased. But very precious promises these are, relating to the gospel church, which will be more and more fulfilled, for He is faithful that has promised. There shall be a glorious church for God set up in the world, in the last days, in the days of the Messiah. Christ himself will build it upon a rock. The Gentiles worshipped their idol gods; but in the period spoken of, the people will cleave to the Lord with full purpose of heart, and delight in doing his will. The word halteth, describes those who walk not according to the Divine word. The collecting the captives from Babylon was an earnest of healing, purifying, and prospering the church; and the reign of Christ shall continue till succeeded by the everlasting kingdom of heaven. Let us stir up each other to attend the ordinances of God, that we may learn his holy ways, and walk in them, receiving the law from his hands, which, being written in our hearts by his Spirit, may show our interest in the Redeemer's righteousness.
