Micah 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 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.
Many peoples will stream toward the elevated dwelling of the Lord and the sanctuary of Jacob's God with the express purpose of receiving instruction in divine ways and then ordering their steps accordingly. The law issuing from Zion and the divine utterance proceeding from Jerusalem function as teaching that directs life toward obedience. Learning the paths and walking in them belong together, so coming to be taught implies a commitment to practice what is learned.
The prophecy does not establish Jerusalem as a compulsory destination where the whole world must journey in order to worship. It therefore gives no justification for gathering population, institutional strength, or material means into a single locality. The divine plan calls instead for the work to be extended over a broader field rather than centralized.
