In the last days the mountain of the Lord's house will be established at the top of the mountains and will be raised above the hills. All nations will stream to it,
and many peoples will come and say, "Come, let us go up to the mountain of the Lord, to the house of the God of Jacob. He will teach us about His ways so that we may walk in His paths." For instruction will go out of Zion and the word of the Lord from Jerusalem.
He will settle disputes among the nations and provide arbitration for many peoples. They will turn their swords into plows and their spears into pruning knives. Nations will not take up the sword against [other] nations, and they will never again train for war.
