“He shall judge

Between many people.

He shall arbitrate

Between strong nations far away.

They shall beat their swords

Into plowshares.

They shall turn their spears

Into pruning hooks.

Nation shall not lift up

Its sword

Against another nation.

Neither shall they learn

War anymore.”

This was a vision of a time of perpetual peace that is often cited by pacifists, exactly the same as an oracle in Isaiah, chapter 2, word for word.  Yahweh would arbitrate and judge all nations.  Then there is the famous saying that they would beat their swords into plows.  They would turn their spears into pruning hooks.  No one would lift a sword against anyone else.  People would forget how to wage war since no one would learn how to do it.  This is the utopian theocratic peace that has Jerusalem rule the world through Yahweh.  It has never happened and probably will not.
