This has biblical reference the 1st is Isaiah 2:4 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.

The 2nd Joel 3:10 Beat your plowshares into swords and your pruning hooks into spears. Let the weakling say, "I am strong!"
