Isaiah 2:2; Isaiah 2:4

2 In the last days the mountain of the LORD’s temple will be established as the highest of the mountains; it will be exalted above the hills, and all nations will stream to it.

4 He will judge between the nations and will settle disputes for many peoples. They will beat their swords into plowshares and their spears into pruning hooks. Nation will not take up sword against nation, nor will they train for war anymore.
