John Wesley on Micah 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.
