'Pruning hooks' in the Bible

And He will judge between the nations,And will render decisions for many peoples;And they will hammer their swords into plowshares and their spears into pruning hooks.Nation will not lift up sword against nation,And never again will they learn war.

Beat your plowshares into swordsAnd your pruning hooks into spears;Let the weak say, “I am a mighty man.”

And He will judge between many peoplesAnd render decisions for mighty, distant nations.Then they will hammer their swords into plowsharesAnd their spears into pruning hooks;Nation will not lift up sword against nation,And never again will they train for war.
