Isaiah 2:2-4
“Now it shall come to pass in the latter days That the mountain of the Lord’s house Shall be established on the top of the mountains, And shall be exalted above the hills; And all nations shall flow to it. Many people shall come and say, “Come, and let us go up to the mountain of the Lord, To the house of the God of Jacob; He will teach us His ways, And we shall walk in His paths.” For out of Zion shall go forth the law, And the word of the Lord from Jerusalem. He shall judge between the nations, And rebuke many people; They shall beat their swords into plowshares, And their spears into pruning hooks; Nation shall not lift up sword against nation, Neither shall they learn war anymore.
