Many nations will go and say, “Come, and let us go up to the mountain of Yahweh, 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 will go out of Zion, and Yahweh’s word from Jerusalem;
Micah 4:1 But in the latter days, it will happen that the mountain of Yahweh’s temple will be established on the top of the mountains, and it will be exalted above the hills; and peoples will stream to it.
Micah 4:2 Many nations will go and say, “Come, and let us go up to the mountain of Yahweh, 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 will go out of Zion, and Yahweh’s word from Jerusalem;
Micah 4:3 and he will judge between many peoples, and will decide concerning strong nations afar off. They will beat their swords into plowshares, and their spears into pruning hooks. Nation will not lift up sword against nation, neither will they learn war any more.
Micah 4:4 But they will sit every man under his vine and under his fig tree; and no one will make them afraid: For the mouth of Yahweh of Armies has spoken.
The verse centers on "nations", "come", "mountain", "yahweh", "house", "jacob", "teach", and "ways". It is saying that the verse draws attention to "nations" and "come", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 1's "But in the latter days it will..." into verse 3's "and he will judge between many peoples...", so "nations" and "come" belong inside that flow. In Micah context, the local focus is covenant, worship, and faithfulness.
A plain takeaway is to answer the verse's own emphasis on "nations" and "come" with trust shaped by these words, not by a vague optimism outside the passage.
