Isaiah 2:2
1 Here is the message about Judah and Jerusalem that was revealed to Isaiah son of Amoz. 2 In future days the mountain of the Lord’s temple will endure as the most important of mountains and will be the most prominent of hills. All the nations will stream to it; 3 many peoples will come and say, “Come, let us go up to the Lord’s mountain, to the temple of the God of Jacob, so he can teach us his requirements, and we can follow his standards.” For Zion will be the center for moral instruction; the Lord’s message will issue from Jerusalem. 4 He will judge disputes between nations; he will settle cases for many peoples. They will beat their swords into plowshares, and their spears into pruning hooks. Nations will not take up the sword against other nations, and they will no longer train for war.
Micah 4:1
1 And in future days the Lord’s Temple Mount will be the most important mountain of all; it will be more prominent than other hills. People will stream to it. 2 Many nations will come, saying,“Come on! Let’s go up to the Lord’s mountain, to the temple of Jacob’s God, so he can teach us his ways and we can live by his laws.” For instruction will proceed from Zion, the Lord’s message from Jerusalem. 3 He will arbitrate between many peoples and settle disputes between many distant nations. They will beat their swords into plowshares and their spears into pruning hooks. Nations will not use weapons against other nations, and they will no longer train for war.
Notes and References
"... In both Isaiah and Zechariah there is a vision of the nations' pilgrimage to Zion. The vision of Isaiah has an almost word-for-word parallel in Micah. There are a number of connections between Isaiah 2:2-4/Micah 4:1-3 and Zechariah 8:20-23: ('many nations'), ('strong nations'), and the cohortative of the verb ('go'). Moreover, the formulation ('come, let us go up') in Isaiah and Micah is very close to ('let us go') in Zechariah ... The direction of the dependence is hard to decide in this case. This calls seriously into question whether the passages actually are mutually dependent. Both might instead be dependent on a third source unknown to us. This, however, does not rule out the possibility that one of them has been composed on the basis of the other. Given the classic style of Isaiah 2/Micah 4, there is no doubt regarding which section could be an imitation of which. Zechariah is thus to be considered dependent on Isaiah and/or Micah rather than the other way around ..."
