Thematic Bible: Nations not warring against each other anymore

The word that Isaiah son of Amoz saw concerning Judah and Jerusalem: And it shall happen in the future of the days the mountain of the house of Yahweh [shall] be established; it will be among the highest of the mountains, and it shall be raised from [the] hills. All [of] the nations shall travel to him; many peoples shall come. And they shall say, "Come, let us go up to the mountain of Yahweh, to the house of the God of Jacob, and may he teach us part of his ways, and let us walk in his paths." For instruction shall go out from Zion, and the word of Yahweh from Jerusalem. read more.
He shall judge between the nations and he shall arbitrate for many peoples. They shall beat their swords into ploughshares and their spears into pruning hooks. A nation shall not lift up a sword against a nation, and they shall not learn war again.

And it will be [that] at the end of those days, the mountain of Yahweh will be established as the highest of the mountains, and it will be lifted up above the hills, and people will stream to it. And many nations will come and say, "Come! Let us go up to the mountain of Yahweh, and to the {temple} of the God of Jacob, that he may teach us his ways, and that we may walk in his paths," for the law will go out from Zion, and the word of Yahweh from Jerusalem. And he will judge between many peoples and will arbitrate for strong nations far away; and they will beat their swords into plowshares and their spears into pruning hooks; nation will not lift up a sword against a nation, and they will no longer learn war. read more.
But they will sit, each under his vine and under his fig tree, and no one will make them afraid, for the mouth of Yahweh of hosts has spoken. For all the nations walk, each in the name of its god, but we will walk in the name of Yahweh our God, forever and ever.
