THIS is what God desires
He will settle disputes among the nations and provide arbitration for many peoples. They will beat their swords into plows and their spears into pruning knives. Nation will not take up the sword against nation, and they will never again train for war, Isaiah 2:4
He shall judge between many peoples, and shall decide for strong nations far away; and 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, Micah 4:3
Beat your plowshares into swords, and your pruning hooks into spears; let the weak say, “I am a warrior.”, Joel 3:10
Then Jesus said to him, “Put your sword back into its place. For all who take the sword will perish by the sword., Matthew 26:52
